I think the thing that aged the worst is Sam's lack of change over the course of the film. She's there to inspire change in Andrew, and that's it. That's the achilles heel of the flick that keeps it from being something more.
There's a reason that this film is pegged as being the prime example of the problem with the "manic pixie dram girl" trope.

Ah, yes, malicious compliance. Find the loophole and exploit the hell out of it.
