Simplified? Yes.
Stupified? No!
imho a beautifully crafted cyberpunk movie that while it does not reach to the levels of complexity of the original anime, it stand it's ground and deliver a great audiovisual experience with a story that is sophisticated enough to rise above most Hollywood movies today but not that much to alienate more mainstream viewers.
This is greatly underrated because it had to stand in the unfair comparison of the anime. I don't believe it is possible to replicate animes so just go and see it for what it is.
A great cyberpunk Hollywood production. It is rare for Hollywood to treat it's original material with respect while trying to simplify it to reach a bigger audience.
