Views on Red 2 differ enormously - My view is that it is a reasonably OK action film, with a fine cast and some good acting.
Watch out for the toe curling action from Dame Helen Mirren and (for me) the best acting performance I've seen this year, by Sir Anthony Hopkins.
Having been brought up in Cold War Germany, there was much in Red 2 to interest me. It is on occasion geographically testing, but that doesn't matter. The film is after all a fiction, and a good thing too.
This film is not a waste of time - the movie business is an entertainment business and not everyone is entertained by the same things. Please bear that in mind. I would suggest that you go to see this film - just sit back and be entertained.
