“Bittertooth” (1/2 out of four) was an insulting mess about two female podcasters (Genevieve Thomas and Autumn Ivy) who take it upon themselves to track down a brutal serial killer (Joe Altieri) and give him a dose of his own medicine by torturing and murdering him but they find out this is far more difficult than they realized. By the end of this trifle, viewers themselves will feel like they have been subjected to even worse torture. Film rambles in about 10 different directions for most of its length and only some stylish gore at the very end saves this from an absolute zero.
