This actually isn't too bad, I thought it would be a horrible mess of cuddly, kissing family fun but its quite dark in places and pretty funny in others. Its not GREAT but its certainly one of Mr Vaughan's better films recently, Witherspoon is just annoying as usual.
It starts off well when they both visit Robert Duvall (Vaughan's dad) and wreck the house, then the next stop after that where Vaughan's old school buddy is screwing his mum LOL! probably the best scenes are there. The third stop at Witherspoons mum is also good, where all the women in the house (granny n all) seem to be sexually active towards Vaughan hahahaha
After that it does go down hill fast and very predictable towards the soft cuddly ending, shame cos it really kicks off as a 'National Lampoon' style fun film....not bad stuff.
