To clarify, Godfather isn't my favourite movie of all time, simply because there is no such movie. I have several other favourites:
300
Shawshank Redemption
Fight Club
V for Vendetta
Avatar (not "The Last Gay-Bender")
Pulp Fiction
Scarface
Tropic Thunder
Rock N Rolla
Inglorious Basterds
Benjamin Button (forgot whole name)
Lion King
Lord of the Rings (all)
Star Wars (all)
And more that I can't remember.
Best series are:
House M.D
Doctor Who
Lie To Me
True Blood
