My Take
Underachiever with no plan and a crush on the class valedictorian just asks her out. No scheme, no makeover, no game. And you spend the whole movie yelling at the screen because nobody around him can see what's actually rare here: the guy is just... good. Genuinely, unglamorously good. Cares about her for real, no angle. Try finding that twice in a lifetime. There is a reason he was the Dobler from the “Dahmer - Dobler theory”. He litterally is the ideal boyfriend (not perfect, who is, but ideal).
▶Official Synopsis
Average student and eternal optimist Lloyd Dobler seeks to capture the heart of Diane Court, a beautiful but unattainable valedictorian classmate. He surprises just about everyone - including himself - when she returns the sentiment. However, Diane's divorced, over-protective father soon begins to disapprove of the match, and Lloyd realises that it's going to take more than just the power of love to conquer all.
