I did enjoy the film, gotta love werewolves, right?
I liked the cast of main characters and found them to be well-adapted to a good story. So, yes, I thought it was great in that sense.
My exceptions are really only two. Firstly, I thought the secondary characters -- the band of werebrothers, were tragically miscast and cheapened any scene they were in. Simple. Secondly, I could tell right away by the studios and initial information that it was not the highest of budgets to be set before me in awe-inspiring effects and so on but I had a difficult time not rolling my eyes at the "retro", to be kind, special effects makeup. That alone was really the disarming factor and made me feel like I was watching a film from about 20 years ago.
So, the long and short of it is if you don't mind somewhat flimsy werewolf makeup and looks, and let the less-than-fab extras or whatever they are, it is a great story, moves flawlessly, has great little twists, and as a person who worked with makeup, lived in Hollywood, knew many people in the industry and am an artist myself...I still watched it and enjoyed it, never once thinking, "Uh, forget this....".
Great for Halloween, by the way!
