I find Joaquin Phoenix creepy in most roles so did not enjoy the movie much but found the technology and setting fascinating.
There’s the LA of the future with and no cars (LA?!!! – it’s actually set in Shanghai). There’s evolved artificial intelligence – as in artificial feelings. No devices – desktop or mobile – have keyboards. Mono earpieces provide the UI to check email, get weather reports etc. The video games are holographic. The mobile devices are hinged and buck the larger, curved display trend of today. There’s no dropped anything even on elevators and trains – so the networks have clearly improved.
In quite a compliment, Wired says the movie will dominate UI design even more than Minority Report did. Go see it for that. If you like Amy Adams that’s another reason to go :)
