This Wim Wenders 'written' and directed homage to Pina Bausch is exactly what 3D is for. Despite the efforts of many an action film that Hollywood projectile-vomits towards us in the name of an extra dimension, none have so far gone beyond what is essentially a gimmicky premise. I may be on the losing side of this war, but I am still to be convinced that a narrative fiction can be told using 3D technology.
Of course, 3D has been in use in non-fiction narrative for quite some time and the results are usually impressive, but still they are limited to the forces of nature that mankind look up in awe: impassable mountains, giant waves, impenetrable jungles ...
Another genre, if you will, that 3D is somewhat advantageous over your run-of-the-mill 2D is in the cinematic representations of performance art: concerts, opera, theatre ... these benefit from 3D, because by their nature we always have experienced these events in 3D. So, a two-dimensional representation always falls short.
