I saw this as a kid and had read that it was the worst of the series. I don't think so! This one is the scariest, weirdest, most atmospheric and most unsettling of the FLY series. I think that if this film wasn't having to be compared to the first two, it would be more highly spoken of. The scene where the heroine discovers just who (or what) is playing the piano in the middle of the night sent chills up my spine. This film has enough ghoulish imagery that really stays with you long after you've seen it (and for me it's been over 20 years). The opening escape scene is ahead of it's time with the mental patient running in slow motion with the title credits over it. Some of the mutants are very quite disturbing to look at and there are plot twists and turns applenty. Basically, no one is safe or sacred in this dark final film in the series. I could talk more but I would spoil it for those who have never seen it. It used to be on television frequently but has now disappeared. However, it's well worth the trouble of finding it. This has the mark of a truly great horror film - it will continue to live in your memory long after your initial viewing. I am wishing for a DVD of it someday. The sad part is that it is the unfavorable comparisons to the original on the part of most critics that probably keep Fox from releasing a video of it. Let's hope they wise up and preserve it on disc before the negative is destroyed. That would be an un-fitting end for CURSE OF THE FLY which is an unsung masterpiece of a horror film.
