The Keenan family checks into a hotel for a family vacation, unaware that they and the other guests are players in a deadly game.
The story is a mostly mashup of 3 horror flicks from the early 2000s: Vacancy, Halloween: Resurrection, and The Strangers, mixed with a little DeathRace 2000, and it has uncomfortable gore on par with Eli Roth films and the Saw sequels. I've got no problem with movies being derivative or gory if they're good, and I'm all for indies, but the overwhelming acclaim on this one is truly baffling.
The story isn't great, and the dialogue for the Kennan family is consistently poorly written (which makes their acting seem terrible). We never get a satisfying explanation for why the game is happening. Tim Reid is way too good for this movie. Jeffrey Combs. Danielle Harris, and Tony Todd give the kinds of performances fans would expect, and most all of the other genre names are wasted in minor roles. If you're looking for Tim Curry and Bill Moseley, it's a long wait since they don't show up 'til the middle of the end credits. And even Dee Wallace couldn't sell bad dialogue.
It's well-shot. The gore is realistic. But it's ridiculously overlong, tedious, inscrutable, and hardly the perfect 10 of a movie that countless (likely fake) reviewers have proclaimed it to be. A 4 is being generous, and it's mostly for the impressive FX and a few decent performances.
