Hmm yep, the steel is a bit of a mess overall IMO. I do really like that blue slip though... just a shame it uses the same art as the steel (I'd rather they switched up the latter rather than the former). I also don't get the choice of purple & yellow for the other slip - makes me think of Cadbury's Caramel chocolate bars lol.
By the way, I think you were actually the reason I even gave this film a watch in the first place mate... I remember someone an Instagram raving about it back when it first came out, so that's when I decided to give it a chance. And thank God too, because I really enjoyed it!
