Lets just get one obvious category out of the way first. I have no doubts that some fancy filmmaking techniques went into depicting the brutality of 12 Years A Slave so barbarically, and that the occasional scene may have been slightly enhanced with some CGI, but - c'mon - its competition is Gravity. Cases have been made that Gravity is the greatest cinematic technological achievement in decades and that it has truly evolved blockbuster cinema - which quite honestly has stagnated into the same repetitive techniques and style and those bold statements couldnt be any more truthful. It also utilises 3D in ways that should put every other film out there to shame; specifically the 36 movies a year that claim to have the greatest 3D ever since James Camerons Avatar. There hasn't been a 3D experience quite like this one - the sensation of all that space debris closing in on you goes unparalleled. It's actually challenging to imagine watching Gravity without 3D. Winner: Gravity
