I love the GitS series, more than most of you here probably... its my second favorite Anime of all time, but I can't really think of a single Live Action Hollywood Anime/VG movie adaptation that wasn't utter shit, so I can't hold out hope that this will survive the horrow of Hollywood regurgitating anything with brand recognition.
Plus, as an adaptation of something people enjoy, with an already largely existing lore/history... It has the same problem a lot of video game movies have. They put people in charge who will skim the "About" section of the wiki about the anime, and make some shit up that kinda fits into the universe but actually really doesn't. Then they cast people who are big names, in an attempt to draw out the crowd who will watch anything (Actor) is in*, regardless of the material, while caring not a spit about how much they actually fit the universe of their source material, thus alienating a crowd of people who might of actually been interested off the bat.
I get why they do what they do, I get why casting a big name actress/actor is the top priority, Movies are a business and a big name is going to attract more people to see the movie that they might not otherwise be interested in... I just don't have to like it ._.
But fuck do I hope it turns out good... there's always a chance it might be an exception to the shit tier stuff we get.
