Disappointing due to hollow screenplay, incomplete IMAX and primitive plot

Rating: 4/10 (18 December 2011)

A very much expected X-Mas premiere disappointed me very much.
The plot is primitive, except for the first 15-20 minutes most actions are predictable with virtually no drama. Action scenes are made with some care but are very mechanical.
The Burj Dubai (Khalifa) was where we expected some stunning blood-freezing action and there it was the action but blood did not freeze... The Moab scene in MI2 was one -- I clearly remember the cinema audience holding their breath, and one cannot stop comparing these two...
Those who go to IMAX version will be specifically disappointed when they realize only few sequences are filmed in IMAX format whereas during the rest of the movie you see coarse film grain and other low-res artefacts of a regular movie format blown to a huge IMAX screen as ... Why is that, dear Tom & Brad, the budget did not allow more?
In the absence of real or virtual drama the whole thing becomes flat and boring -- I wish they considered hiring Robert Towne again, for example... .
It is not very often that some characters are so irrelevant to the plot that а movie could live without them. Despite superb acting of Mashkov (russian cop Sidorov) I really miss why this character is in the movie at all ! Take him out and... nothing changes !
Paula Patton (Jane) - I am sorry but Jane is as "persuading" in the role of a field agent as Halle Berry was in JB Arctic story.
I'd better stop now and will not go into smaller details (read- spoilers). The nice side is that at least some of the sequences ARE filmed in IMAX, the opening soundtrack seems to have been re-recorded and is excellent, there are some nice areal IMAX shots of Dubai and Mumbai at night. Most of Moscow seems to have been shot in Prague or Wroclaw and does look very fake.
What else - Tom plays as he usually do but because of the primitive plot and dull screenplay there is nothing left to remember or comment. Knight & Day is what You remember, not MI-4.
I personally believe any review/rating higher that 7/10 for this one is a 90% fake ("stimulating") whereas 8-10/10 ones are 103% such.
