The dramatic success of Robot & Frank hinges the credibility of the two main protagonists. Frank Langella effortlessly plays a retired jewel thief Frank Weld who’s starting to have problems with his memory.  His son Hunter (James Marsden) takes the only logical course of action and buys him a robot home help. The movie is set in the “near future” and so the idea of a deferring care of the elderly to machines seems worryingly credible. Plus, in this case, there is not a huge amount of love between father and son. Or so it first appears. There's more going on with this movie than first meets the eye. The plot is smarter than it first appears and makes some interesting social commentary.
