“Unfriended: Dark Web” (*1/2 out of four) was an unbearable follow-up to the 2014 hit about a teen (Colin Woodell) who comes into the possession of a new laptop but soon finds that the previous owner is watching him and his friends online but also will do anything to get it back and they are unable to exit their online watch or else they will be killed. It’s much easier to exit the movie instead. More-or-less a rehash of the original but unlikeable characters, uninvolving story, and unpleasant violence make this a request not worth answering. Inauspicious directing debut for noted horror writer/producer Stephen Susco
