This is weird for me to write this, because I didn't really even watch that much TV back home, and I don't even own a TV in Japan, but my friend turned my on to the show Unubore Deka (2010). I've only seen a couple of episodes of varying J Dramas (never watched even close to a full one through), but this one had me hooked. The show is hilarious, and it reminds me so much of how my friends shoot the sh!t.
I feel kind of sad though because it was actually still on air when I first moved to Japan (August 2010), but I'd never heard of it. Now I've just watched it and it's a quarter through 2011 already, and the show feels kind of old. Like I hate saying ("Oh, it came out last year..." or "It came out in 2010...")
