I watched both 'Horrible Bosses' films back to back and it's clear that the first movie is the better of the two. 'Horrible Bosses 2' has its moments but lacks ideas and the originality of the first film. The guys are a lot more stupid in the sequel, they reminded me a lot of the Hangover trio. Whether that was deliberate or not I don't know, but they weren't that dumb in the first film.
By the standards of the average comedy movie, it's not bad. I laughed a few times, which is more than can be said about a lot of comedy sequels. Like in the first film, Aniston and Sudeikis are the highlight for me. Both are brilliant in their roles. 'Horrible Bosses 2' isn't as bad as some would have you believe, but there's a clear lack of ideas here.
