He just felt that The Dark Knight was a bit high-brow, a bit intellectual, and while those aren’t necessarily bad things, he didn’t want Iron Man to go that route, which I can appreciate.
As can I - a film sequel should pattern itself on the original rather than its rival. Still, I certainly express no regret over passing seeing this film if
The Dark Knight was 'high-brow and intellectual' in contrast.
The Dark Knight was non-moronic and smartly written - a relative rarity, I'll concede, in summer fare (where once upon a day the latest garbage the Wachkowskis were peddling qualified as intelligent) - but I don't think the film is difficult at all to understand for your average moviegoer. Given the box office success the film is receiving, I believe the average moviegoer concurs.
