Ghost Ship (2015)

Same concepts all around can't spoil b/c it would ruin the entire movie.
However, what makes it alike/different:
1. Male/Female lead fighting evil (only here there's an ambiguously romantic relationship)
2. Obvious titles give you the setting
3. State of the existence of the lead males are exact
All of the above works for Train of the Dead which I will Recommend.

Both are horror comedies with bromance. They both have ghosts in them and they're stuck in a haunted place.

I can't spoil the story b/c their the same excluding two separate things, one being glaringly obvious:
1. Ones on a ship, the other is on a boat
2. In Ghost Ship, the leads are dating. In Train of the Dead, they're not.
