It's hard to fault this movie. Literally. I was going to rate it as an 8, but I have to give it a 9 because I can't think of anything about it to criticise.
The plot is rather simple. Frank is a confused older man who is finding it difficult to take care of himself. He is given a robot medical assistant who is programmed to do only one thing: help Frank. Frank resists mightily at first, but soon Frank improves remarkably and takes up his earlier vocation: stealing jewels. It turns out that the robot's programming does not extend to obeying the law...
This film is interesting, surprising, heart-warming, intelligent, thought-provoking, amusing, understated, well written and well directed. It delivers first-rate performances by first-rate actors.
It defies categorisation. Is it science fiction? A heist movie? A family drama? A melancholic feel-good story about aging? It has no shootouts, no car chases, no superspies, no superheros, no martial arts scenes, no demented villains. What it does have is character development, good writing and a nice story.
Kudos to Schreier, Ford, Langella and Sarandon.
