I would recommend this a million times over Ao Haru Ride (I gave that a 3).
The story is fine. I expected the melodrama from Io Sakisaka, but the decently and mature enough characters make up for it. Sure, there are some communication problems, but given the age of the characters, it's understandable. In the end, they all find a mature way to resolve them.
My first impression of the girls was that they were going to be childish and annoying, but they surprised me being far more likeable than I anticipated. I ended up rooting for them halfway through (especially Yuna).
The acting was good (nice debut for Marika Suzuki) and the sound aswell, with some nice music. The art was easily the best part. Jesus, the are some great shots and everything looks beautiful.
Overall I find myself enjoying the film, getting really invested at some parts. It's no masterpiece but it's a nice time.
