When this movie first came out in '06, I saw plenty of people talking about it all over the net. 2 years after Shaun of the Dead, it seemed like there was finally going to be a new renaissance of horror comedy. There really wasn't much of one, but that is an entirely different topic for another day. Fido kind of fell to the wayside after a bit, though, in the shadow of Shaun.
But you want to know something? It shouldn't have. It's really a great little film, worth it's own merit. The only thing it shares in common with the more famous zombie comedy is the fact that it IS a zombie comedy, and they run with the idea of having the creatures as pets after we've managed to 'tame them'.
Imagine if the 50s wasn't about the fear of communism or nuclear war, but zombies. You pretty much have Fido, but there's really more to it. The main character, Fido, has more behind the facade of a drooling and brain-crazy slave to his nuclear family. Billy Connolly is...incredible in this. I honestly didn't even realize he was Billy Connolly at first, without the eccentric beard and long hair. Everyone is really amazing in this movie. I can't express enough how great Fido is, as a horror comedy fan. If you take your horror too seriously, avoid it. IF you have a sense of humor, I'd definitely suggest 'Fido' for a Halloween viewing this year.
