The premise doesn't make sense and the characters don't act with any consistency or with any naturalness or any common sense. It has received lots of praise and even Director Tarantino thought it was great. I guess it started the "battle for survival" genre of movies so it deserves some points for boldness. The excessive violence doesn't feel very horrifying since none of the characters seem like real people, just mannequins. The plot is full of holes and contrivances. The dialogue is silly. Maybe a kid's video game was the progenitor for this movie. Its not a real movie; just a violent video game for people who don't want to make the effort to press any buttons.
