I agree that the announcement and releases of images and the teaser at comic con was very early, but it's hard to find the happy median with most fans....give give give. Why did you show it so soon? When are you going to show something else? Give us the film already, etc.
I for one am simply happy with what we've seen so far. I think DC is at least taking the right approach and taking a good long while to make the film to produce the best film they can. I have high hopes for this and although I wasn't a fan of Jesse being cast, I'll admit that after seeing this, watching Z-land again, etc, he is a great actor and with the right script and inspiration I think he will do a very good and unique take on Lex that will be a breath of fresh air compared to the happy, joking, "scientist" we have seen in previous versions.
