It pretty much should from anyone to be honest.
I do have one thing to add this time around though: the finale depends on a trope not often seen.
The Good Parents.
However the finale in From up on Poppy Hill is the exact opposite. It depends on Umi’s mother listening to Umi, and then setting up a meeting with Shun’s father to fix the problem. That Shun’s father would help is unsurprising by that point of the film.
It’s a lovely touch, and I think that From up on Poppy Hill is a stronger film because of it. Those little details can sometimes make all the difference.
 And in media focussed on teenagers generally to be honest.
 Some of which still apply in From up on Poppy Hill.
 Shun’s father is awesome. His absolute insistence that the adopted Shun is his son in ways that matter is just beautiful.
