Yeah, if you're interested in trying new things, find someone who has Firefly and borrow it. If you like the show, even a little, you'll love the movie, Serenity, but I would recommend watching the show first. After you've seen the movie, there are... some major changes... yeah.
Gears of War is the first game I've been impressed with in a long time- it has an original storyline, incredible graphics, and actually manages to pull off the gritty realism that so many games try for.
