Watched this last night in 3D. Better than I expected, enjoyed it tbh. 3D felt very natural, nothing much wow but great depth and nicely immersed.
Fear being that this as a stand alone film doesnt work due to the sequel the ending it's obviously pushing for. If it flops\doesnt make a packet I can't see Disney commissioning a sequel leaving the story unfinished. Personally id liked to have have seen 20mins at the end added to tie the story up. I'd go for a sequel if one ever transpires though.
I asked Amazon about what was going on W.R.T to this. I got an interesting reply the listing was placed on the website by error. So that's why all items have been withdrawn for the moment. I'm assuming that Zavvi use the same sources of information and thus they made the same mistake.
