Mimic is one of those generic horrors with nothing that really stands out. I don't like 90's gritty movies and this one is definitely one of the them. Recycled plot from Alien plus awful score make this movie almost unwatchable, add to that bad character development (Josh Brolin is criminally underused in this) and you got yourself one of the worst Del Toro movies. Some parts were entertaining but Del Toro made much better movies later.
