It depends on each one.
I will always prefer SF TV series. Other people may prefer a football game, other people TV news, music, or documentary, etc..
Taste not is discussed!
Depends on how you think it can be fun (relax).
I always chose the movie because I love S.F. area, for I always learn something new - I do not understand what I could learn from a football game. But - as I said, each in his own way.
However, if I were to give advice, I would advise everybody to watch a movie or to read a book - something that brings something new, something which to be teaching.
