Saw this film last night and I have to say it surprised me. Totally enjoyable experience. The casting is spot on, Matt Damon has the charisma to pull of the romantic humour as well as the integrity and willpower to fight the system. Emily Blunt manages to create a character that you can imagine wanting to beat the odds for.
Thankfully, very little time is spent on explaining why the 'Angels' are here, even the one or two lines of exposition are a little off putting. Instead they decide to focus on the meat of the story, should you accept your logical fate or fight for your gut instincts.
What it made me realise was that getting the emotional punch right cancels out any of the fancy pants special effects: even the really subtle ones here were extraneous (like smart-paper schematics on the notebooks). I think it was also wise to drop any complications to the plot. All I cared about was what the Hero was going to do next, that's what a good story is all about.
PS: How many filmable Philip K. Dick short stories are left?
