Overall the movie was decent. The cast played their roles very well. Dan Stevens, Alisha Weir, and Kevin Durand were the movie's standouts. There was also a decent amount of gore. The movie jumps around between horror and comedy a fair amount, so don't expect a full-on horror movie.
The ending was a letdown though. Spoiler ahead - Frank gets turned into a vampire and ultimately plays the bad guy which was ok, except they could have gone a different route with his character and given us a bit of a surprise ending. Instead, we get the same old cliche ending.
But if you've got free time and don't know what to watch. I'd recommend giving Abigail a go.
