Watched "Horrible Bosses" on DVD the other night.  No, it's not "Citizen Kane," but it's a very decent light black comedy, and I did laugh quite a few times.  Kevin Spacey has the most delicious part (typical Spacey, but still fun).  However, Jennifer Aniston does a nice turn as well, and is almost unrecognizable in her "s l u t t y dentist" role at first.
