What are they 'being called out' on?
If it's the artwork then that's a bit harsh. It's not like Zavvi has any say over it. This is just another poor decision by Fox following on from their dour looking Batman: The Movie (with a rubbish front and stuntmen on the inside), that God-awful range featuring Speed, The Day the Earth Stood Still and The Rocky Horror Picture Show and the re-release of Robocop (with a giant Robocop in a tiny street). As I said, this seems to be the one and only image Fox have created for The Rogue Cut as it appears on every announced release worldwide.
Again, with the 3D, it's not going to happen. Fox have (to my knowledge) never released an extended edition of anything in 3D that was post-converted, yet waste time with 3D conversions of Predator and I, Robot (go figure).
I really don't get the point of complaining about these things. Nothing's going to change Fox's mind. They stuck to their guns with those previous designs, just as Disney will with Ratatouille and Anchor Bay did with their Punisher (with the wrong skull and title font). Besides, aiming your complaints at the retailer is a waste of effort. All you can do is complain to the studios and keep your wallets shut on release.
