Personally, I love the relationship between all of the characters, and are people I would actually want to meet. I also not only enjoyed the Japanese sub, but the English dub, I think is really well done.
What I didn't like was the swearing. I know it's common in language now, but it seemed random at some times. I also disliked how some characters, ie. Maho's friends. I found them a bit annoying, but overall I enjoyed this anime and I recommend it to anyone who likes music.
