must see horror movie

Rating: 10/10 (8 January 2005)

This is one of my favorite movies if not my favorite. It has excellent special effects,but thats not why its so good, Its story uses paranoia ,suspense, fear, and gore to scare you.
The special effects weren't computer animation, they were all robots, which gives it a more organic and real look. they used real flamethrowers and I think real dynamite.
The movie's ending doesn't let you know if they make it or not, if they killed the thing, or if they are the things.
there is a game that is supposed to be the sequel to the movie. I played it , it's a good game , but it doesn't do a good job of being a sequel to the movie.
