In "Avatar: The Way of Water," the director James Cameron pulls you down so deep, and sets you so gently adrift, that at times you don't feel like you're watching a movie so much as floating in one. From time to time he brings you to the bottom of an alien sea, shot with stunning hyper-clarity in high-frame-rate 3D and teeming with all manner of surreally strange fish — all oddly shaped fins, decorative tentacles and other vestiges of an otherworldly, faintly screw-loose evolutionary timeline.
You can imagine the fun (and the headaches) that Cameron and his visual-effects wizards must have had designing this brilliant ocean-floor nirvana. You can also see an astronomical budget (reportedly north of $350 million) and an extraordinarily sophisticated digital toolkit at work, plus a flair for camera movement that, likely shaped by the director's hours of deep-sea diving, achieves an exhilarating sense of buoyancy.
Much as you might long for Cameron to keep us down there — to give us, in effect, the most expensive and elaborate underwater hangout movie ever made — he can't or won't sustain all this dreamy Jacques-Cousteau-on-mushrooms wonderment for three-plus hours. He's James Cameron, after all, and he has a stirringly old-fashioned story to tell, crap dialogue to dispense and, in time, a hell of an action movie to unleash, complete with fiery shipwrecks, deadly arrows and a whale-sized, tortoise-skinned creature known as a Tulkun.
