I've also seen it. I gave it the benefit of the doubt because of Alyson Hannigan. Well I have to say, what a load of unfunny, bottom-rung junk and one of the worst movies I ever did see. Yeah it's a parody, it's not a thinking movie, so just switch off and enjoy it right? Well that wouldn't be so hard if it actually was funny in some shape or form. Most of the scenes are mere references to it's original source and I have to say, the comedies it parodies are much funnier. Honestly, don't waste money on this you're better off watching Meet the Parents or whatever else you have in your collection that is parodied here.
Nothing to see here, move along!
