Isolation is a very odd horror/thriller, but it works. The storyline isn't the best (animal experiment gone wrong), but its doable. The thing that makes the movie pretty good is the characters, suspense, and fear of the unknown. The actors are not well known, but they are good, they make it a lot more believable. Also, they act in a realistic manner, which also really helped. Over all its a great suspense film. Yes, the idea as a whole is pretty trite and corny, but the director made it work into something good. Its a good above average horror/thriller that is actually pretty underrated. I rate this 7/10. Rated R for violence/gore, language and a scene of sexuality
