This film made me want to rewatch Walk Hard and Spinal Tap haha... Yes - I'm a Motley Crue fan, and yes - I've read the book. This biopic is very cheesy and predictable though and the acting is almost always average at best. As for the "crazy" behavior and whatnot - I have spoken to several musicians who had toured the same venues around the same time, and they all said that this movie was only a "mild" version of what was actually going on, which was wild and much more dangerous. I suppose everything is very PC now, so it's not easy to show too much insanity, but still...
