Damn good, judge for yourself This is the type of movie that you can easily decide whether or not it is worth your time. The plot says it all. Stuck in a sauna..why are they stuck and what will happen to the people? Nothing more, nothing less.
If this plot sounds cool to you (which it did to me as a fan of Open Water, Buried, Frozen, etc), then you will enjoy the movie. Period. Good acting, likable characters, etc.
If a movie can leave a lasting impression on me, it worked. I will always be reminded of this movie any time I see or go into a sauna. Not that I frequent saunas, but you get the idea. This doesn't mean it was a great movie. It wasn't. But it was definitely above average. Scout Taylor Compton is a legit face in horror now so I enjoyed seeing her. I give it an 7/10 (horror movie scale) but I'm bumping it to an 8 just to offset some negative reviews.
