The larger problem I have is how annoying the main male character is. But, I guess this is needed as a plot contrivance or else the movie wouldn't happen. The majority of the plot is housed in a submerged house, and this didn't help with the movie. They follow a minor Lovecraftian plotting, but the set is waterlogged and confided, but only limits vision. Not scary or inventive.
