I agree that many action filmmakers have gone over the top with relentless, endless "cappers", where one action tops the preceding one in endless succession without taking a breath. Ultimately it becomes tiresome and numbing because there's no time to build up tension (oh my gosh, will they make it?) before the next whammy hits you.
Peter Jackson also has no self control and can't figure out when a scene actually has ended, dragging such action out interminably. I was pretty done with him by King Kong, and then suffered through the first Hobbit film (via a screener), and I simply will not waste any more time on him on his movies. The man proves my current signature (the Welles quote).
