Good idea for a list. I agree with most of them, in fact, except SEVEN SAMURAI, NO COUNTRY and LEON. I think LEON is pretty great for an testosterone-fantasy film, but it does have an excessively-rabit fanbase. NO COUNTRY FOR OLD MEN is great, but no greater than twenty other films released in 2007...
Finding Nemo and Napoleon Dynamite are at the top of my list. I can't say I agree with man of your choices, but that's why it's good sto psice things up sometimes. Gone with the Wind deserves its place on the list, though.
