I watched this last night and laughed through most of the movie. I say "most" because there are some serious moments. Josh Meyer is definately an underappreciated actor and they justify this fact in the "behind the scenes". This is another pearl of this movie. The extra features are excellent.
Cameos by up and coming music artists in the movie are well acted as well and will surprise you when you find out who they are. One example is Ronnie Winter. I kept telling myself, " I know that name. Where do I know it?" He is from Red Jumpsuit Apparatus. They did that song, "Face down".
One of the funniest cameos is by Jenna Jameson. It was a short cameo but I kept laughing at her performance and additional interview in the extras menu.
Just look at the stars on the cover and you can see how good it can be.
The only negative is the rare moments in serious scenes where the tempo kind of drags you down. Also, the awful clothing design. I kept saying, "What are they wearing and who needs to get fired?" The attempts to be trendy just came off as poor fashion sense.
Well worth the watch though since fashion sense is a very small negative.
