Wow, I had a different vision for the movie in my head. Just from the early posters, I thought Chappie would be less of a child, but a rebellious teenager who doesn't know any better; and Ant Diewood would be his bad influence.
This is totally a 180.
People keep on mentioning Short Circuit, and while there are notable differences, when Chappie starts talking at the end about 'I am alive, etc', yeah, it does have a 'Johnny 5' vibe.
There's a part of me who thinks some of the skepticism steams from the fallout of 'Elysium'; a well meaning movie that didn't hit all the right notes. But I'm getting the feeling a lot of Neil's ideas steam from his teenage years doodling in his notebooks. It just FEELS like it because with Elysium (hate to pick on it though) felt like interesting themes that were coming from the limitations of an angsty but smart teenager.
