Recently I made a list of 5 movies I consider "must-see's" and posted it here on AVITW. The nice people at a fantastic website called OnlyGoodMovies.com spotted my brief list, linked to it, and turned me on to their own various "must see" lists and movie reviews.
One big highlight from Only Good Movies was their "75 War Movies to See Before You Die" list. Check it out!
Spoiler alert: Their #1 is Patton
