The good thing for libraries about paranormal suspense dramas in the M. Night Shyamalan tradition: unlike much horror, they rarely trade in cheap gore, sex/nudity, or vulgarity. The bad thing: the suspense-based plots almost always hinge on a satisfactory twist ending to justify all that has gone before. And if you don't have that...
...Well, you have Mystery Spot, from Texas writer-director Mel House. The setup is a decent one. Somewhere in the hinterlands, a motel operates near a mostly forgotten tourist-trap attraction, the "Mystery Spot," whose exact appeal and nature is left deliberately vague. The whole spread is run by a jovial middle-aged gay guy (this picture is notably "inclusive" with cast diversity and un-Hollywood types), who keeps his late lover's ashes in an urn.
Despite its obscurity, the place has a few guests. They include schlubby freelance film-casting agent Nathan (Graham Skipper), auditioning a procession of would-be actors for an unknown project with prepared, portentous questions, then mailing the video results off to parts unknown. These sessions seem to send all the participants into strange and troubling altered states of mind, and Nathan may have serious problems of his own. He claims to have a science background, and mystery parcels in his car hold only "soil samples" from the Mystery Spot.
Then there is melancholy Rachel (Lisa Wilcox), who says she "killed" her own husband in a car wreck. Then there is the detective-like intruder parked outside, taking notes on all the people coming and going. It goes on, for perhaps ten to twenty minutes longer than necessary, before the revelation that we are watching a kind of ghost story. Even that does not explain all the elements very clearly.
M. Night Shyamalan himself had difficulty being M. Night Shyamalan from time to time, and viewers are more likely to find the slow build to the payoff a frustrating one, though the actors all put in fine work, and leading lady Wilcox is well remembered by fans of the vintage Nightmare on Elm Street series. No knife-handed demonic Freddy types violate the moody ambiance, which some audiences may find commendable; others will wish there has been that level of excitement. Optional.
