Phantoms is a 1998 thriller about a Colorado town being terrorized by a monster, and it was actually filmed here. But, that may be the best thing about it. 

5280 put out a list of 'scary-bad' movie sets you can visit in Colorado to get into the spirit of Halloween, and suddenly I have an itch to watch Ben Affleck in Phantoms, which apparently, is not exactly The Shining (5.4 out of 10 stars on IMDB). It was, however, filmed in part at the historic Hotel de Paris in Georgetown.

Could it really be scarier than Gigli, though? #Bennifer
