5. TRON: Legacy (2010)
Id always maintained that if 3D was to actually work as an advancement of film, it needed to be used for something that further cinema as an art form. The obvious idea would be to do something akin to The Wizard of Oz and A Matter of Life and Death; use both 3D and 2D together to represent two separate worlds. Both Coraline and Alice in Wonderland blew this chance, proving their conversions as a mere cash-in. And then TRON: Legacy came along. In the pre-release coverage, first time director Joseph Kosinski claimed to be doing what Id been waiting for; in the story of a man sucked into a computer to save his father, the real world was going to be 2D and the computer world 3D. When the film came out, this proved to have no impact. For starters, the 2D real world lapsed into 3D at points, but worse, the switch to 3D had no impact. You can argue the dimensions were the wrong way round, but the key to the problem was that 3D in its current form wouldn't work as an artistic extension of cinema.
