I'm not a huge fan, the snow sequence in the end was very confusing.

However, the action scenes were frenetic and exciting with particular praise going to the anti-gravity fight scene in the hotel. This is a great anthology moment if I ever saw one. Cinematographically, this is great with the director going from spectacular bird's eye city views to closed-in face shots to show the emotions with a whole variety of angles between the extremes.

The shooting is masterful. We're never really lost in the action except perhaps when the characters look too much alike in the snowy dream layer. Speaking of which, this part felt very much like a James Bond movie and I kept thinking the "hero" was too good to be true.

Then again, we're in a dream and who knows how much training the operatives have... I was also bugged by the fact that rules were explained for the dream layers and yet some seemed to have been ignored. I know it's "dream logic" but if you intentionally explain them, mostly stick to them so we can continue suspending disbelief. An example of this is how the guy in the hotel is supposed to have 2 minutes left until something has to happen, yet if you combine his sequences (because it alternates between 3 different stories/dream layers at that point), it's way more than the time alloted.
