The last twenty minutes saved the whole movie

Rating: 5/10 (9 June 2015)

As much as I would love to enjoy this movie, I just couldn't. I'm a big music fan but this movie just does nothing for me.
First of all, it's rare that I find NONE of the characters likable. I just hate all of them twenty minutes into the movie. And at thirty minutes, I was already wondering if I should stop watching it.
The racist and homophobic jokes are utterly tasteless. What was the director thinking about when producing the movie?
If it wasn't for the last twenty minutes, I would've given this movie a 4/10. The plot is slow until the last twenty minutes; the major swerve at the end is nice but is not really plausible for me.
I'm seeing Pitch Perfect 2 and I don't have a high hope. It's a pity, because if the plot and characters play out well, this movie could have been one of my favourites.
