My cousin got me into it when i visited in early January (2010). At first i was slightly ashamed, it's not something i would imagine i would normally watch and somehow it is both brilliant and terrible at the same time.
As of last Friday i have watched up to the season 2 finale, it was great.
I adore Chuck and Blair as a couple, and as individual characters. I found Jenny annoying at first, but then she got better and now (end of season 2) she s annoying again. Yep that made sense... anyway. Dan is also quite annoying at the moment. I'm liking Rufus and Lilly too.
I want to watch season 3 but season 2 ended on such a happy note, and it's been making me happy for a while, and i need that right now, so i'll have to postpone it.
