Carnosaur 2 is the best entry in the series. If you ignore the rubbish dialog, this film might come across as decent for a (very) cheap horror flick. Compared to the original Carnosaur, this one is a masterpiece. The gore is less severe and obnoxious, The creatures are shot in a such a way that for most of the time they don't look too rubbery. Most importantly however is the fact that the plot is far more coherent than the original, Part of it has to do with copying almost directly from the well written screeenplay of Aliens. For a cheap budget, the set design is pretty good and gives the movie a dark, industrial feeling. The acting is stiff and unrealistic, but again, next to Carnosaur it is acceptable. I would not recommend this film to everybody, only to extreme horror fans.
