Why would Grace continually run away from Ethan anyway? I get it at the start but surely the car sequence in Rome would have been enough for her to realise that she was way over her head and needed to trust the guy? Strange character.
@Dirty Schwein, you missed the point with Asian lady. She hadn't turned at that point, but the AI had calculated she would eventually turn. So they betrayed her first.
I found the CGI in the final section in particular to be really frustrating as clearly the stunts they performed were epic, but the way the CGI was handled made you doubt what you were seeing. Shame.
Its clearly setting up for a new generation of Mission Impossible with a new team. I enjoyed the film, it was funnier than I was expecting.
