I had to chuckle when I read this. My kids and I watch Tora! Tora! Tora! every year on Dec. 7th. The kids always want to watch Midway right afterward so they can see the Americans win! (BTW, if you watch them back to back, you'll discover that some of the same action scenes/footage were used in both movies - we have fun picking them out)
That said, I think this movie cancellation is ridiculous. The film is excellent and does a masterful job of presenting both sides of the attack.
