For me, it would have to be Marvel, their lies at the start that this movie will be more faithful to the comics than Ang's movie never stand well with the fans, especially me, did they not learn from the X3 fiasco of the screen-writers telling lie after lie about the movie? Throw in Abominations terrible 're-design,' the reason for which makes no sense and would have applied to the comics design also, not to mention some possibly story points (Hulk possibly killing a/some humans?!), not to mention a bit of a rushed production time which could see the CGI in the movie suffer and this all makes me for one not look forward to the movie to much.
The trailer was good, but so were the trailers for X3, a dreadful movie and FF2, Ghost Rider and Blade:Trinity, which all turned out average at best.
