“Happy Birthday Hannah” (* out of four) was a lame, amateurish horror story about a girl (Natalie Klein) who is tormented by guilt about letting her younger sister drown years earlier and on the eve of her sister’s birthday- she and her none-too-bright partner (Brandon Burkley) are tormented by sights and sounds of the girl around their house. Practically the definition of the term low-budget horror with photography that looks like it was filmed through someone’s used cell-phone and the film isn’t so much edited as patched! Even besides that, though, this clunker proves to be yet another rip-off of “Poltergeist” and (naturally) “Paranormal Activity”. Sometimes dead isn’t better
