If there is one Hollywood team that you can always rely on to push back the boundaries of taste it’s the Farrelly brothers. Say It Isn’t So is only produced by the pair but owes more than a passing sniff to their brand of comedy of misfortune. Animal rescue worker Gilly (played with extreme Keanu-ness by affable Chris Klein) falls head over heals for the worst hairdresser in existence (Heather Graham). Their whirlwind romance culminates in engagement and consummation and that’s when it all goes wrong. You see Gilly is adopted and it turns out that his real parents may be none other than his potential in-laws. The plot is wafer thin at best with the majority of the action derived from Gilly’s cringe-worthy and harebrained schemes to prove to Graham that they aren’t related, which of course just end up convincing her even more that theirs is a forbidden love. Along the way, there is a cast of misfits and comedy clichés for Gilly to contend with including the legless pilot sidekick, Graham’s smarmy millionaire fiancé and his redneck brother. There are few laugh-out-loud moments, as the script pretty much begins and ends with the idea that the more Gilly tries to clear things up, the more mess ensues. Both leads appear slightly dazed, as if trying to fathom out what made them sign on the dotted line, and the direction lurches from one gross-out moment to the next. There are some redeeming features: the ending is suitably uplifting and there’s a lot of fun to be had in anticipating what misfortune will strike the hapless Gilly next, but in the end this is one "Farrelly" movie which pushes cow abuse too far.--Kristen Bowditch
