I always find it so hard to choose!
At the moment I'm loving Brothers & Sisters, only started watching it recently and nearly at the middle of the final series. I love it, so well observed and well done. Does that count as a sitcom? If not, probably Big Bang Theory at the moment.
Book - I love Wuthering Heights though Pride and Prejudice comes close.
I love Yesterday too. I always find imagine quite haunting after an exhibit in the Beatles museum, all white with a piano and it playing. I love the Beatles songs though. Even went to Strawberry Fields memorial when in New York.
Film - errrm, will have to think about that one.
