Saw it, loved it. Vince Vaughn is the best smart ass out there these days, and Fred Claus is the perfect opportunity for him to display his smart ass-yness. There is alot of silliness in this movie, which is good. There's a degree of predictability, but in the end it's tied up pretty neatly. And Kevin Spacey is great as Clyde. The "Rubberneckin'" number is AWESOME. Chris "Ludacris" Bridges creeped me out as the D.J.; his head was weirdly cged on a tiny person's body. He was good, but watching him gave me the heebes.
Go see it.
