Not of this Earth is actually a really good b-movie. Im not a movie critic, so i dont know what actually constitutes a good movie by their standards but I do enjoy watching movies and telling about them. This movie is guaranteed to keep you entertained. the acting is really quite good, as well as, Traci Lords is super hott and has a great body. I think i like her better in actual movies. plus Lenny Juliano plays a good part in this flick. In my opinion he is a great character actor, he brings just enough comedy to every movie to keep you paying attention to him. I believe this is one of Jim Wynorski's best movies. but this is definetely not a movie for children. Its not scary or gruesome but there is a good bit of nudity and sex scenes. I rate this movie at least a 7 out of 10.
