The filmmakers toss subtlety out the window in favor of fun, in your face chills that stick their landing. They also know how to stretch their meager budget; the ghosts of past patients in this asylum play a major role in inducing goosebumps.

Finally, a little self-awareness.

The filmmakers seem unaware that they're beating a dead horse. As the uniformly annoying characters stumble around, screaming and cursing, we don't give a hoot for their survival.

The pacing is good and the scares are effective even on a repeat watch... All in all, it is a good scary movie, it’s a fun time, but as you watch it multiple times it gets less effective.
