This movie never had a chance of being good - it's a modern horror movie based on a board game. Still, it could have been campy fun. After all, it is a board game. But no, Ouija is not fun. It's very, very boring.
Everything about this movie fails on so many levels. The writing doesn't have a single original or interesting idea, and it doesn't even make sense in the end. The acting is dull, though that's largely due to the fact that our characters spend the majority of the film moping around their houses and at school. There's no way of gaining momentum of suspense when nothing is happening. The characters play the board game a couple times and there are a handful of cheap jump scares and bad effects. That's it. The direction is flat and indifferent. Worst of all, it's not scary in the least.
Ouija is the absolute bare minimum for a horror movie, completely devoid of energy, inspiration, and any interest in telling an original story.
