Query: 2.5 STARS: Entertaining and very funny movie, but...

"Of Unknown Origin" really is a rather entertaining and humorous movie. It's more of a dark comedy than horror, though. Peter Weller stars in this movie about a man who has his life turned upside down by an unwanted guest in his home. The acting is good as Weller does a terrific job as usual. That being said, I thought this was supposed to be a horror movie, and from that standpoint, I was disappointed. I guess it's a brand of horror, but not the kind that appeals to me in that sense. However, as a dark comedy this movie does very well. Just depends on what you're looking for.
