Currently, my three addictions are;
The amazingly brilliant 30 Rock. I can easily say it deserves all the accolades it's received and going to receive. I'm only on the first season, been watching it as FIVE repeated the first season but I love it so so much. Even though FIVE are apparently airing Season 2 either this month or the next, on one of its sister channels, I have a feeling I'm going to jump the gun and watch ahead...
The Office (US/An American Workplace). I originally disregarded it, for ages. Ricky Gervais is my favourite comedian, and it was one of them tragic remakes -- How wrong I was. Five seasons, and still plowing. Again, I love the characters and I find it much easier to get to know and understand characters within sitcoms without the usually off-putting laughter-track or studio audience.
And, lastly Smallville. I don't evoke half as much emotion over this series, and I suppose that is why it's not exactly award-winning. The mythology episodes are possibly its strength at the moment (S3). I'm intrigued about all the characters and the implied teen-show love triangle. I'm more excited about where it goes in later seasons.
