One thing I LIKE (from the preview)
Is that it is NOT just a scene for scene remake of the original. Sometimes remakes are the EXACT SAME STORY THE EXACT SAME LINES JUST DIFFERENT ACTORS. I like that the story is more sophisticated and addresses some modern sociological problems.
For example in the original they just picked a bank to rob because they wanted the money but this movie is addressing how corrupt the banks have become and they are robbing the bank as revenge for the bank screwing them over, it makes what they do more morally justified and makes me especially want to root for them. I am sure banks were corrupt back in 1979 when the original version of this was filmed but that movie did not really address it.
In the original they just wanted a lot of money so they could really enjoy their last few years of life. In this they are getting a justified revenge and they even said that any money beyond what the banks unfairly screwed them out of would go to charity. The original gang were not so altruistic.
I like it when a remake addresses modern social trends and makes a story a little more sophisticated than the original did. This might actually be a better movie than the original and that is rare for remakes.
