Yes, I'm aware of the things that they could've made way better but in a good anime, there's either an ending that satisfies you, confuses you, or pisses you off. None of these three are bad but that depends on your "taste" in anime. Me personally, it made me really happy. The ending was just perfect (before end credits), and the fact that they came back to where it all started brought tears in my eyes.
Only reason why I didn't give this a 10 is because of the disrespect on Utaha, who's supposedly one of the main characters. Not only was her screen time limited but the lack of her development as one of the main characters bothered me. On the other hand, Eriri was given what she deserved with a "proper" goodbye to her "what could've been relationship" with Tomoya.
The actual ending (after credits) hit me right in the heart, I was brought back to reality after seeing what could've been the end of their relationship and their status as a couple after giving up on their dreams. Later then being reunited with all the members was just the cherry on top of the movie, it really couldn't have been any better than that.
So if anything, don't drop the series, trust.
