A friend of mine was recently voicing his complaints about his Netflix account. He is a huge sciFi fan and when searching for his favorite SciFi movies would always find many versions of knock off movies right next to them and in one case had even chosen the wrong movie for delivery. I did some research and found what I was looking for at scifiwire.com. I had no idea how many mockbusters were really out there. Here are some of the best. Princess of Mars actually takes credit as inspiration for Avatar on the cover.
