It's the nearly two hour PopCast Xmas Ubertacular !! During this massive festivus, JV takes out his frustration with NYC hipsters, and we review the troubling documentary ''I Think We're Alone Now.'' Plus, as a special Xmas Bonus, the PopCast breaks new ground as we welcome, for the first time ever, actual guests on the program. First, hilarious comedian and actor John Flynn will review Burlesque and Tron. Then, ardent sci-fi guru Tina Sena will tell us about her favorite science fiction programs and also the shows she hates.
