I was OK with the first one - some of the writing was cheesy and the villians were sub-par, but I am curious as to why they altered the design of the bike and jacket - those were some of the best design choices in the first movie.
I try not to get too excited by trailers these days - any terrible movie can have a crafty trailer cut together to make the movie seem totally awesome, so I will have to reserve my judgement until I see the movie.
