Lights Out is another example that horror movies today are getting effort again. Yeah, The Conjuring, The Babadook and a few indie horrors have already proved that, but Lights Out would have been just a throwaway concept. Except it fully utilizes its idea and the characters are worth rooting for and actually smart. The allegorical core feels underdeveloped in spite of spending a chunk of its plot devoted to these backstories. The villain isn't so interesting, apart from her abilities and shortcomings. But the final act is worth the payoff. Maybe not much for the ending. Overall, it's a lot of fun than it is scary. For just another trip to the cinema, that's all you need to know.
