Coming from a non-musician.

This movie was bad. Not terrible just plain ol bad.

Although (as I stated) I am not a musician in any way, so I don't know how accurate the drumming was. I did not feel any sense of presence when the drums got played.

The Two lead characters (that being the main drummer and J. K Simmons character) where pretty good in terms of acting. But in terms of care I had for these characters developed in the story and the scenes that where meant to be intense that where ultimately left on a sour note, I say this movie is a mess.

Without spoilers I would even like to point out that the ending is terrible. It builds up a cool scene that lasts a good amount of run time, just to instantly cut it with no conclusion. But unlike Inception, this movie didn't benefit from such a gimmick.

Story - 5/10

Characters - 5/10

Music - 2-3/10

Acting - 7/10

This is a movie that would've benefited from having a longer run time, but even then it would have had to have been a lot better to have had a chance to hit the 5/10 range.

In terms of musical films (yet again coming from a non-musician), this one is pretty poor compared to it's challengers in the same category.

3/10 wouldn't recommend but isn't necessarily a waste of time.
