“Celebrity Crush” (*1/2 out of four) was a sordid horror melodrama about the star of a cult-B movie in the 1980’s (Oliver Robins) who is obsessively stalked and then kidnapped by a deranged fan (Alissa Schneider) of that movie and he has to fight her to the death to escape. Writer/director/star Robins actually was the star of ’80’s horror classic “Poltergeist” but that’s too much sophisticated irony for this trashy timewaster. Schneider’s amusing performance is a plus but you may feel like taking a shower when this is over.
