This is just a personal opinion and I tried to be honest as much as possible, if you disagree feel free to said why. So let begin(damn i am going to die after finishing this, also noted that everything here reflect on what i observed from the show)
SS1) Ok so let start from the root where the show just came out, and Disney is still over watching it. What got you to watch SS1 in the 1st place, when you first look at it? ,Svtfoe isn’t any different from a normal cartoon with a normal plot which is ez to get , Star is this magical princess that is just crazy, and bubbly, she come to Earth knowing nothing about it and well let just said the unlucky guy who is Marco was the first to met her and the one that had to deal with her “star-ness”. She declares herself his friends ,while Marco try to get away from her as fast and as far as possible who wouldn’t XD,too bad she is moving in with him :P . Later Star and Marco got a deep moment of understanding about how Star didn’t had a choice about coming here, and how Marco also don’t had a choice about having to deal with her,that when Marco start to open up to her, then after a monster fight for some reason he actually wanted her to stay that when Star give him their first hug. Good story from the start and that when the “Starco” shipping begin for me, so Starco as you may call it, it the main reason why i got sucked into this series. And throughout the rest of the season we just got more little moment between them,also with the story about Marco guiding Star on Earth,there are even time when they didn’t get along and question eachother but in the end they still are bestfriends.Awwww good old time but every good thing had to come to and end right?
SS2)Well nothing much to said about this one, the entire season was based around Drama and how Star realize her feeling for Marco only for him to date Jackie. Marco been crushing on Jackie for a long longggg time, so there is no surprise that if Starco were to happen one of the two,either Marco or Star had to lose each other for them to admit their feeling OR the creator can just NOT do Starco and let them be friends with their own crushes if they didn’t like the idea. But that isn’t the case here is it?, like I pointed out above main reason the show was so good was because of the Bond between Star and Marco, so if they follow the “just friends” idea it would just be funny ,cause they had been trying so hard since SS1 to tell us that this two share a really fond bond that made “everybody” had to ship them. But there are still confusing things in SS2 that just made little sense, for example after the “Sleepover” episodes, it hinted that Star had feeling for Marco already, and is jealous when he gives his attention to Jackie, and then we had “BonBon” where Marco was invited to a dance by Jackie herself that was unexpecting(look like someone got their eyes on him)but Marco already had a date that Star but when he asked if she was Ok with it and she said yes easily, welcoming him to go, only when she sees the look those 2 give each other did
Star become depressed all night weirdddddddddddddddddd if she already had a thing for Marco and doesn’t Jackie near him why act sooooooo like this(out of place).
There is also that time in “JustFriends” when she invites Jackie to a concert which at first only had her and Marco just to turn herself into the 3rd wheel? I don’t know if this is naive or the writers just wanted someone to get heartbroken in the most obvious, stupidest way possible(who would invite their love rival to a party that had just you and the one you like????). After that blahblahblah we got to Starcrushed when she admits her feeling then left blahblahblah BFM then Marco chases after her to help then blahblahblah SS3.
I would also try to ignore the fact that Star smile(rather disturbing) while melting Toffee alive in “Toffee”. Is this still a kid show?in SS2?hard to tell. Oh and Marco cry and punch a literally “hole” through Toffee when he thinks Star is gone. Starco?nah “friend” do this toooo -Don’t you mean friends in life-………….. SS3)The end is here, so let start where the creator left us. Toffee was defeated(destroyed) and Marco spend some of his summer with Star on Mewni and they never talked about the crush-thing, but judging by “ScentofaHoodie” they had good time hanging around each other even with Star is crush on him, then there was a temporary goodbye in which this 2 dork take forever to said goodbye, and Star go crazy missing him and become “in love” with his hoodie when Marco just left for like 5sec,then with Ponyhead coming right over after she heard everything that had happened(-but she had to get her hair done first-WHAT a true friends)and convince Star she doesn’t need his hoodie cause he will always be in her heart and Star herself know this.AWWWWWWWWWW well enjoy the feel buddy this is the last Starco moment you get. And based by the frown and sigh on Marco face when he leaves Star and smell his Star scented hoodie , i thought that he had at the very least figured out some of his feeling for Star and question if dating Jackie with all of this is the right thing to do. And here come the game changer:
1)Jackie confronted Marco about Star and he is still able to said that she is just his friends -_- you disapoint me man, this is a really a dick move, Marco you still try to date her even when you had feeling for someone else , you act like you are hurt and that you loved Jackie but I don’t see any of it when you are always with Star.
2)After the breakup Marco instantly go back to Mewni to see Star(yeah you love Jackie alright -_-). Now let take look at Star, ok 1 episodes you were in love with Marco the next you had feeling for Tom okkkkkkkkk, then they dated okkkkkk that was fast.(WHO THE F*** WRITE THIS)
3)Marco united with Star in “LintCatcher” for her to said Star:“Oh Marco…….is so nice to see you….what are you doing here” :O :O :O………………..the way she said it, so Marco is like a stranger to her now, then Star parent was like confused about him coming back WTF?why would you think he will never came back?WTF, then there is a fact about Mewman being assholes let see:River give Marco a meat blanket which he treasures so much(clap clap well done), he also lies to Marco about letting him being a knight, and the knight of Mewniiiiii were being a bunch of retards that think highly of them self (yet those sissy lose and surrendered to a mutant bird and his RAT army)
4)The show also bring up that it had been weeks off-screen since the last time Star and Marco seen each other, so they kill all contact between the two out of the blue, and just let them forget about each other simple(FACEPALM) 5)In lavalake there just more sour taste throw into the viewer:Star give Tom one of Marco hoodie,she also call Tom her mess up twin awwwww I see what the writer are doing here, is like Star and the show is replacing or projecting Marco (GOOD WRITING? DO I NEED TO HIT YOU WITH A WATER BUCKET), also based on how this new “Star” of SS3 act she also forgot about Marco birthday, he never celebrated it. So SS3 new version of Star is callous and shallow, while Marco being not really like able is being bash to the ground. And that’s a rap.being not really likeable is being bash to the ground.And that's a rap.
