Starcrushed

Simple, its a climax episode, every time there is an episode where there is 2 parts is always the best

Star ditches the Diaz family's summer vacation party in attempt to avoid having to confess her feelings to Marco; The Magical High Commission hunt down Ludo/Toffee in an abandoned magical temple.

Both the first and the third season finales ("Storm the Castle" and "Conquer") include action, emotion and drama; however, the second season's finale episode, while maintaining these themes, manages to use already familiar storylines (Star and Marco's relationship, Ludo and Toffee as the main antagonists of the series, etc.), and braid them wonderfully together into a satisfying episode.

The episode brings the storyline into a more serious setting, introducing darker magic, painful confessions and sudden revelations. The first season included more energetic and light-hearted tones, whereas the following seasons brought the series into a darker spotlight.

Said episode moreover includes one of the most thrilling magical battles that the writers have offered us, in spite of including neither Star nor Marco, who usually are the sources for adventures and magic.

Throughout the entire series we see the progression of Star and Marco's relationship. "Starcrushed" manages to develop their relationship by exposing them to awkwardness and emotional confessions. The pair is usually together in harmony, however, by using the previous episode's ("Face the Music") conclusion - in which Ruberiot, Star's princess song composer, reveals Star's feelings for Marco - the writers use a thrilling formula based on the "will-they-won't-they"-question.

One complaint, however, is the lack of action regarding Star and Marco. The episode is beyond entertaining, nonetheless, due to the emotional moments that are introduced through Star. The conclusion to the episode is furthermore thrilling, exciting and satisfying, as it brings Star and Marco into darker adventures and magic.

This season 2 of Star Vs the Forces of Evil has been more clinical and more intense. from silly adventure in season 1, now it's getting more story-arc format, more serious adventure, more awkward thing and more shipping (?).

this episode take place after "Face the Music", when Star and Marco now are avoiding each other awkwardly after Ruberiot revealed Star's crush to Marco in Song's day. in other plot, the Magic Commissions are trying to find Glossaryk and the spell book when they are encountering Ludo.

this episode was speechless, tbh. I really love all the aspects written in this episodes. the awkward teen relationship was written well, the fight of Toffee vs Moon was very intense and epic, Lekmet's and Star sacrifices was very emotional, and the decision to put cliffhanger and silence outro was genius. very genius. I honestly still shook with this, especially the ending when Star had to leave Earth for Mewnies, leaving goodbye's words " I do have a crush on you", to Marco. it really shook everyone, including the fandom.

honestly, when we talks about best cartoon season finale, we would discuss about Sozin's Comet, Weirmageddon, or some titles they've known, but this is no joke, and should be on the discussion. really, people, watch this episodes ( for better feel, watch Face the Music before Starcrushed ) and you will try not to cry ( or worse, try to be not frantic)
