I just bought Coraline having missed it at the cinema but being a fan of both Gaiman's original story and Selick (and his Burton-isms) I figure I can't go wrong with it, right?

But it came with both a regular 2D version and a fancy 3D version (and glasses) - is it really going to be worth faffing about with the gleggs and sitting up closer to the telly for gain the full 'immersive' experience?
Should I do as the good Doctor Kermode says and ignore the 3D gimmick and get on with watching the movie for what it is?
