Me too. But I'm the kind of guy less bothered by a battlecruiser sized submarine in the canals of Venice than I am by the fact that Tom Sawyer would have been 60 in 1900.
One is insanely cool, the other is just wrong.
The sub was stupid. But League had the same element that Avengers and the TV show Heroes had: a group of individuals who have distinct talents but who are even better working as a unit. That, to me, is America-—individuals becoming great by maximizing what only they can do.
