The plot is a horrid mess of a blatant King ripoff...
Just finished watching this - it was plagued by horribly bad acting and directing. The scenes where she is slowly, casually 'jogging' from room to room while fleeing for her life from monsters made me literally laugh out loud at how awful it was. It was such a bad acting/horror cliche, it would have fit right in in 'scary movie'... along with the rest of the movie.
Aside from the fact that it now holds a place among the worst 5 movies ive ever seen (among queen of the damned, ghost game, etc.), the entire hospital/vampire plot is a complete ripoff of the novella "Little Sisters of Eluria" from Stephen King's "Everything's Eventual".
I hope King sues their asses for this.
