"Unbowed, Unbent, Unbroken"
GoT is currently my favorite book/television series, and the only reason why I shell out the $$ for cable television.
I just finished reading the first 4 books and have watched both seasons. Thus far, I can't tell which I prefer, they both have their strong and weak points...so I guess I'll reserve judgement until I see how they handle the impending OMGWTH?! events that will be taking place during Season 3.
Having a favorite character is the Kiss of Death for them, so I try not to have one - it tends to vary from book to book anyway.
Least favorite characters are Joffrey
(I could watch Tyrion slap him all day) and Ros
(she serves no real purpose other than HBO) I'm also not really a fan of the Starks in general - their propensity for making bad decisions is mind-boggling. Arya's ok though.
