No spoilers. I saw the only review was a non-fan of the series so I thought I'd give something that might be more useful to those looking for opinions.
The movie was okay. It gives you the closure you're wanting for each of the five girls, and leads into that closure with a heaping pile of the drama you know and love from the series.
It's because of this that it's so unfortunate that it was a little bloated. It know it's adapting the final few chapters from the manga, so it's hard to say where the blame lies, but it feels like it spends a bit too much time getting where it needs to go at times it felt like it was stalling just for the sake of it. I think if this stuff all happened in a regular episode I wouldn't bat an eye, but sitting down for a movie, you sort of hope for a more focused, polished experience, and they missed the mark a little on that.
That's not to say I didn't enjoy the movie. As a fan of the series I was happy with how the ending was handled (even if my top girls didn't come out on top :c). It has some great moments that let the characters shine, which is why I loved the series in the first place, but I don't think it hit the heights of the second season for me.
Basically, if you like the show, you'll be happy you saw this and experienced the end, but don't expect anything too crazy.
Also for those of you wondering, Uesugi does make his choice with some time left in the movie, so you do get a sort of epilogue for how everyone deals with his choice, and he does pick one girl, no cop outs here. Even if he didn't pick the one I wanted, I think they did a good job of selling why he picked the one he did.
