Canary tells a pretty simple slice-of-life story about a band trying to get back together and make it to the upcoming festival concert. It's not a very complex tale, but despite that, it's a bit hard to follow at points. However, some of the scenes are presented pretty decently, and it has some alright moments here and there.
The real problem I have with it are the characters, though... as they're just entirely bland and uninteresting. It makes it difficult to care about the story at all, especially one as simple as we have here.
The animation is passable, but it's bogged down by the crummy
artstyle, which is detailed, but has some pretty terrible moe character designs.
As for audio, I liked the soundtrack, which is to be expected in an anime about a band. However, I watched it in Japanese, and the voice actors were not great. They weren't terrible, but a lot of the voices were pretty standard, annoying-sounding high-pitched girls.
Overall, there really isn't much of any merit here, but it's also not incredibly bad. It seems like it's a decently made anime, but everything about it's characters and overall style really didn't appeal to me at all.
