The storyline was very different and unique. At the end there was an odd event that made it sound out of order. The whole "I have your heart" thing seemed impossible because Kanade was there long before Otonashi was. It seemed like they also jumped into the "I love you" faze way too fast. You also don't get to see a whole lot of the member disappear at the end, like TK, Nota, Shiina, etc. I felt like that music didn't fit the mood at all, but other than that all the other sounds fit well. The characters were well designed, but at the end they started adding all these weird details like Matsushita(the fifth) losing a bunch of weight when he shows up for the last fight. The anime had just the right amount of serious and funny moments, overall not a bad anime, but a few things could've been better.
