i think this is wishful thinking. i cant imagine (it still hasnt happened as well) a big company paying millions on licensing and then to transform and swap a whole running and selling product.

fact is that batman need to be rated 12+ years to attract most customers. so there goes everything that could make a movie dark or the joker some sort of scary villain.
same with movies like spiderman or star wars. if you aim for teenagers or the broad mass as audience you simply cant produce 3 things:
+scary and dark atmosphere
+complicated plot
+deep character development

i know how i was as a 14 year old and most important for me as for everyone else at this age where fast, easy and effect loaded movies.

so bb2 will be as spiderman3 or any other blockbuster in the last 4 years: a flat and hollow arrangement of special effects combined with a easy and predictable story and no real character development at all.

and this is ok because movies like this should be made as well. but to be honest i would rather see another batman
