Well, trailers don't look good, and just playing the odds with DC films I'm not optimistic,
HOPEFUL yes, very very hopeful, but not optimistic.
This is a reason? I've seen plenty of bad trailers for movies that I ended up enjoying very much. And I've seen great trailers that featured movies that ended up disappointing me.
Posters have been awful, trailers have been awful, all the rumors have been awful. Any reason to believe that this isn't a where there is smoke there is fire situation?
It sounds as if you have determined that this movie will be awful no matter what.
