MacGruber was one of those movies where the situations were humorous but often they were hindered by the acting. Other than Kristen Wiig most of the actors in the movie were really bad, except for a few times when Forte was especially funny (like when he blew up the van).

There were some well set up gags too, like when MacGruber did the celery in the ass thing. It wasn't that funny when he was doing it, but it pays off big when he is eating celery in the next scene. You could tell it was a saturday night live movie though, because for every good scene there were two boring ones that weren't particularly funny. That said, when the jokes landed I found myself cracking up a lot.
