“Heartbeat” (*1/2 out of four) was a ridiculous exploitation thriller about a news reporter (Nicole D’Angelo) who finds her life in danger when a news story she publishes results in several murders of people around her and she finds that the killer may be targeting her next. What sounds like (and should have been) a crackerjack and tense thriller is completely undone by slipshod production with dumb dialogue and some terrible acting. No one should be too surprised by film’s ending but you’ll likely be glad it’s over by then. D’Angelo also co-wrote the script.
