While the trailer does look good, it just seemed to out there. The dark knight, though by no means realistic, kept things relatively unextrodinary for a superhero movie and focused more on a good plot which is what made it so good for a superhero movie. This trailer makes the sequel seem a bit over the top, but alas its just a trailer. Still a few months before I will know for sure if this movie lives up to its predecessor in my eyes.
On a side note though it was a horrible pun, and very obviously coming, I couldn't help but laugh when batman said "this isn't a car" at the end of the trailer.
