Cross of Iron
Stalingrad
Der Untergang
Das Boot
Saving Private Ryan

I would have included Band of Brothers, particularly the "Replacements" episode for the nice tank action and a surprisingly accurate Jagdpanther, but that series is highly inaccurate, as is the book its based on. Building up the myth of the 101st and Winters at the expense of the Fallschirmjager is an inexcusable offense in my book.
