Ok, i'll comment now on the artworks because unfortunately Batman & Robin will always exist. Sob, sob.
Firstly. I think the rear arts of each slip look great. It's very '90s' (yes, I'm aware Batman was in the 80s but only just) and they match the steelbooks very well. Colour schemes overall are ok
but I'm a bit hit and miss on the steelbooks themselves. The generic looking city scape doesn't do it for me and I think they should have focused on the gargoyle statue type buildings as well as
making it a bit of a darker design overall. The box is probably the worst with a gold logo, and if you removed said logo (and all text) then you wouldn't know it was Gotham city or a batman boxset
if you had never seen it before. You could guess but 'Batman' doesn't spring to mind for me with that design. Hell, it could be Sleepless in Seattle!
Why not the Batman signal being shone above the city on the box and then forget the title? Everybody knows what that is. Plus, there is already text elsewhere.
The front poster arts will be done justice by HDzeta, I don't think anybody has to worry about how nice they will look as lentis and colours will pop.
As for the front designs of each, I think I would much rather have this than the logo for the first movie and then character designs for the rest. They will all match better that way.
However, if Batman was just being released on its own then I would rather have just the logo itself but unfortunately this is a set with the atrocious B&R in it.
