Rolling over in their graves?

Robert Zemeckis and his crew for dismissing a film they have obviously worked hard on from the just the trailer alone but I see no logical reason why they shot A Christmas Carol in performance captured 3-D. None what-so-ever. It certainly can't have been for an easier life as A Christmas Carol can be performed adequately enough with very few sets, actors and most importantly, not a big load of the American dollar. For those with long memories, I didn't think much of the trailers for Beowulf around this time two years ago and one of the more shockingly unexpected articles I've read since I started movie blogging was when Harry Knowles completely creamed himself over the picture because by then the knives were well out of the drawer, and Beowulf along with this technology was ready to be slain, mocked, and sent to the gutters. In the end, I very much dug Beowulf ... but even in the pre-release days when I thought the movie looked liked trash I could still understand why Zemeckis used the technology. With all it's creatures, it's ancient old myths and larger than life legends and sequences, it benefited from a technological push over the harder jumps. But for A Christmas Carol -Where's the benefit in having Jim Carrey play all the "Ghosts of Christmas Past, Present & Future" when he is barely recognisable outside of his other role as Scrooge? Where's the benefit of having Scrooge fly to the moon - does that really add anything to this story? You dig up the graves of Alastair Sam and George C. Scott, and you ask them whether the trailer for Disney's child baiting A Christmas Carol works? Wait... don't give Zemeckis ideas because at this point he could probably resurrect any actor that ever lived with his animation and exploit them for his own purposes.
