Started off with a message. A deep message? Depends if you understand and sympathise with the protagonist. I did and thought it was a brilliant set up that got me thinking. I also know people who wouldn't have cared either. It's not long into the movie before it becomes much simpler. It pulls some emotional tricks with flashbacks and speaches but they seem a little contrived and don't hold up to the start. I thought the emotional journey of the protagonist was hit and miss. The isolation was good as it did justifies the actions and motivation, but l didn't feel the isolation beyond that. The suffering was unclear. His relationships with the robots worked to fill gaps but they didn't have much depth. A lot of potential was unexplored.
The music was great. The acting was good. The message and initial idea saves it.
