I don't enjoy raining on people's parades but... they basically just slammed two movie posters/recycled art (clashing, mind you) together and called it a day... That's uninspired to me... Even disrespectful to this brilliant movie and artwork they chose for the front. This full gloss with anything else in the back... heck they could have left it plain with some embossed vines encircling it and it would have been perfect.
It's sort of cringe worthy that people are okay with this. If they put more than 30 seconds of time into designing these things everyone would be happy and they'd be selling these things out instead of hoping they'll sell out from hype alone... Instead they're put on fire sale for £6.99-10 a few weeks/months/days later.
