Trailers Anonymous

Now I've seen the director's previous films (Nightwatch and Daywatch) and I found them wholly confusing and underwhelming. And yet, addict that I am, I'm absurdly excited by the trailer for Wanted. I'm like some kind of pathological goldfish, coming to each film with renewed hope no matter how many times I've been disappointed. And I blame the trailers.
The main problem, probably obvious to everyone else out there, is that being able to make a good trailer just means you have two minutes of good footage. With editing and, perhaps more importantly, music any film can be made to seem good. Case in point, the Matrix Revoloutions has a pretty good trailer and is one of the worst (or at least, most disappointing) films ever made. I suppose all this really means is that the advertising companies are doing thier jobs - flashy and well edited trailers makes thousands of idiots like me spend money on their films.
It's opium for the masses...
