One horror film from the 1970s that I think is a prime candidate for a proper remake is "The Town That Dreaded Sundown." It is based on a true story. In 1946 a killer known as The Phantom Killer murdered five people in the space of a few months, and terrorized the town of Texarkana, Arkansas. The original movie was pretty good. The scenes with the Phantom Killer are extremely effective (except one murder scene was pretty hokey and was created specifically for the movie, according to what I've read about the case,) but what makes this one a prime candidate are the scenes involving the police investigating the murders. They are played WAY too much like a "Dukes Of Hazzard" TV episode. They almost destroy the film which is a shame since the murder scenes were so well done. If a proper remake were to be done, they should take the entire story seriously. They should not make a mockery of the police investigation, and they should also actually *SHOW* the small town resident's fear and paranoia, not just have a narrator mention it. Also, the Phantom Killer murder scenes should be a touch bit more realistic as to what actually happened. I know nobody knows for sure anymore, but I highly doubt anyone was murdered
[Show spoiler]by tieing a knife onto the end of a trombone and stabbing them while playing a little tune. 
Anyway, done right, this could be a fantastic remake in my opinion.
