The Dark Knight

The Dark Knight is curently breaking records every where you look: All Time opening Weekend (beating Spider-Man 3 by $4m), Biggest single day gross, Fastest to $100m etc.

In fact in 3 days it's already grossed over 75% of the total US gross of Batman Begins and is 44% ahead of notorious flop Batman and Robin.

How is it doing this? There are multiple factors that could be behind this massive take:

A) General love for all things Batman.
B) Superb and innovative viral campaign.
C) Respect for Batman Begins and desire to see the follow-up.
D) Excellent reviews.
E) Curiosity about Heath Ledger.

Which do you think has tipped the balance? Feel free to comment.
