Even if they left the backs blank it would be an improvement, those weird little pictures just make it look cheap. I like your idea of the skull across the backs of all the releases.. and in a perfect world they would be debossed around the edges and embossed skull and bones. If all steelbooks had put that kind of effort and money into the design and production of steelbooks, we would be parting with our money happily, I would be happy to pay premium prices for premium treatment, everytime.
Zavvi have dropped the price on these now, but the backs put me right off, even at £15.99 they're not worth buying (not worth it to me anyway).. i have to say, it was the first film I really liked, so the artwork was gonna have to be something special for me to buy them all.. and sadly, I don't think they are special in any way not even the front.. but..£6.99 and I'm in!
