I have seen White Caste and Guantanimo Bay. The 2nd in the series was a let down in many ways, but did have some funny parts. I was worried that 3D Christmas would be a disappointment and that the only funny parts were already shown in the commercials. Well I pleased to say that it kept me laughing throughout and made good use of 3d. This one a good story with several subplots, maybe a couple too many, but overall awesome.
