At a risk of sounding slightly sacrilegious, on first viewing I'm kind of inclined to put this right up on a par with 'Shaun of the Dead'. Now, given I view Simon Pegg as an unquestionable comedy genius, I realise this is a rather big claim. And to what extent you agree with that last statement may be a good preliminary gauge of whether 'Fido' will appeal to you.
In a way the comedy picks up where 'Shaun' left off, except we're back in the original 1950s Living Dead-era stereotypical middle-American small town. The Zombie Wars are over and zombies themselves are becoming more well-adjusted, useful members of the community. This, so we're informed at the outset, is largely thanks to the scientific advances made by the good people at Zomcom - a nice play on romantic comedy perhaps?
The beauty of the film lies in its dead-pan depiction of a respectable neighbourhood maintaining core values while making a place for zombies and the special hazards they pose. The charm and balance with which it does this is near enough perfect. Themes you might expect from a more mainstream kitsch comedy come through - the veneer of good clean living, keeping up appearances, repressed emotion, muddled parental values, social decorum and the plight of the alienated individual.
It's a story told with happy heart and wide appeal that is brought to life vividly by the film's all-round strong cast. It's one of those works where it really shows through that everyone involved got a kick out of taking part. It's also fun imagining what Billy Connelly learning his script must have been like...
So in conclusion, it is probable you will appreciate the humour of this film unless your father tried to eat you.
