I was recently asked by the BBC to comment on whether Avatar would herald in a new revolutionary kind of cinema, and whether its CGI and 3D effects meant that it would be far more immersive and spectacular than anything we’d ever seen before. It’s a shame they asked me before the film had actually been released. On the radio I warned: ‘Don’t believe the hype’ and that turned out to be pretty much the case, except I wasn’t prepared for how bored I would be.

Here’s the real problem with 3D. The 3D plane that detaches itself from the screen and heads towards you is itself 2-dimensional, creating an effect that is explicitly artificial. Yet as the 3D effects continue our eyes adjust and we no longer notice it, as was the case in Coraline, Up and Avatar. 3D has to draw attention to itself to be noticed but by doing so distracts you from the film itself.

3D cinema breaks the primal illusion of cinema, that a flat image can appear to have depth. 3D suits its status as a novelty for good reason. It’s 2D cinema that’s the truly immersive experience.
