I haven’t seen ‘em all but Rotten Tomatoes has. Here’s what their editors picked as the top of 2007: see - http://www.rottentomatoes.com/m/no_country_for_old_men/news/1700054/.
I agree with “300” and “Ratatouille” since I’ve seen ‘em and know that they are worth your time. The rest are most likely decent rentals though.
And with that; it’s New Years Eve. Do you believe it? I have a few issues with the concept… Still, the calendar must be satisfied.
Happy New Year, Gentle Reader, may it be all that you hope it to be.
