They always bloody do this with 3D films, why have 3D slapped on the art.
They must realise by now Steelbooks are adored mostly because of the artwork, if a steelbook doesn't have good artwork then people will just avoid it. Having a massive 3D in the middle of it is going going to draw people in.
Seriously the worst part about this is that you can't complain anywhere for them to change it, not just for this one but all future releases. Feedback would help them make better steelbooks and better steelbooks from them means they will sell more...or quicker.
Pass from me....maybe in the future they will re-release it with better artwork.
