BitTorrent probably...
I'll wait to rent it when it comes out, but I have to say I'm getting pretty disappointed with this season. I started watching the show from the beginning on Fox, and thought it was hilarious. Last night's episode, however, was pretty lame. I don't remember there being so many flashbacks in the first seasons. It seems like they are having trouble stringing together a 22 minute plot these days.
Anyhow, it sounds like the movie gets the show back on track, so I'm looking forward to it!
