I have seen so many killer bear movies, and none of them have really pulled it off really well. I am pleased to say that this is the best killer bear movie I have ever seen. How you can train a bear to do all of that is completely amazing! The plot is pretty good, but not great. But at the same time, it's quite simple. People are getting killed in the Grizzly Maze and when a bunch of rednecks come by and start killing the bear's babies, you can imagine it doesn't help the situation at hand. The bear is now angry, and goes on an even bigger rampage to kill everything and everyone.
The acting was good, especially from James Marsden, Piper Perablo and Billy Bob Thornton. Billy Bob Thornton plays the professional, greedy, annoying bear hunter, and to be honest, he was hardly in it. He was only in it for 15 minutes.
Overall, it was a great movie. I was never bored. I was always interested. The script was a bit weak, but the main actors did well with what they had.
Overall, I would give this movie an 8/10. The final showdown was pure genius! And Bart The Bear is the best acting bear I have ever seen! Definitely recommended.
