I've always wished that characters like Meredith and Creed could get a little more time in the spotlight. The few times they have gotten attention, it's been hilarious! Like the episode where Michael runs her over, and then they have ridiculous fun-run for rabies!
Someone I never liked: Jim's ex, Karen, I think? She was very catty.
I'm dead serious; meredith needs more time in the spotlight!! Her character is way too priceless. I kind of wish Roy had never left the show, he had a very interesting character, there was deep potential for various plot lines there.
I watched Season 3 over the long weekend. It's difficult for me to pick a favorite character; every actor is so perfect in their role. There's not a weak link in the cast.
Steve Carrell, however, is a freaking genius. Michael is such an ass, but you can't help but root for him. His character has so many dimensions.
I love the UK version. I actually worked on the Slough Trading Estate for a few weeks, had my own genuine OFFICE experience (not a pleasant experience!).
