XTRO is on this list for one simple reason. It is the only horror movie beginning with the letter X that I can remember seeing. I admit it. I do not remember much about this movie at all. I think it is about a human woman that gave birth to a child fathered by an extraterrestrial. No idea if that is completely accurate. The only thing I do remember is that we got it from the video store and I believe some of the effects were the sort to gross mothers out. I have to track down a copy of this after all these years.
