The best part was how they built up Gary as the sympathetic underdog getting revenge for Todd Glass being voted off last week, and using shots of Todd being a total asshole to build it up. Of course, Ant looked like devil incarnate in this episode with his whole "I'm so smart, because I'm gay!" schtick and him being a manipulative bastard.
Ant did redeem himself somewhat by calling Gary out, thus giving Gary the chance to take him out. So, at least he goes out with some dignity. Then, of course, they ended with that "Ha Ha! I'm not the real puppetmaster!" thing from Ant. He obviously means Tammy, the head of the comic mafia, who is going to have to cut up one of the roommates and scatter their body parts all over at some point to win.
I admit, I've still yet to see "Big Trouble." But I'm surprised that you found it to be so bad - the book was hilarious. Then again, The Firm and Hannibal were decent books that turned into not-so-decent movies.
