The "sidekick" is an annoying con/thief.
The problems lack depth, and severity.
And Most importantly, the issue in the movie is, a let down. The bad guy is scrapping old/outdated robots, and recycling them. For what purpose we don't know, but the machine makes shinny ingots.
But why are they evil?? It's stated throughout the movie they Knew this was happening! Robots collect outdated robots and they're recycled. So what's the issue? What's resolved when the recycling plant is destroyed?
