The haunted submarine
Interesting concept...the haunted submarine. I'm serious. You have haunted sea-going ships, haunted castles, and haunted houses all the time. I've even seen a movie about a haunted 747 passenger jetliner. I've seen a movie about a haunted train.
Like the haunted 747 and the haunted train, each features the elements of limited and restricted spaces and the inability to leave the location for obvious reasons.
BELOW was an interesting movie. I read some criticism on this movie. But it deserved better. The movie was on a short, limited release. I watched the movie late at night to an almost empty theater. It was plenty spooky to watch at the time.
I can actually recommend this movie as a good ghost story. Two-and-a-half stars out of four. That means worth a good look.
