"Battle of Britain" with Michael Caine was bogged down with a horrible love story sub-plot.
"Midway" suffered from a horrible sub-plot as well but produced some great quotes ("You better shape up, Tiger, or some hot-shot Jap pilot is going to flame your a**!") and memorable scenes (Heston's flaps flopping in the wind on final approach to the carrier).
The best of the best:
"Twelve O'Clock High"
"Tora! Tora! Tora!"
and my favorite, which I'm hoping will be released on DVD soon,
"Gun Camera Footage of World War Two"
