People keep saying that the packaging is crazy or weird like Inart purposely made it obnoxiously big when I feel like that isn't the case at all. Everything that's included needs to be placed
somewhere in a box. Just look at the contents of the 2 pack rooted version in the picture below.
How do you package it so that it's magically smaller than how it currently is? Where do you put the two encased rooted sculpts? Where does the giant diorama jail cell base go? Say they made the box deeper instead of it being skinny + wide like it is right now. Great, it's now the same big box but instead it's vertically very deep and tall.
The box issue simply stems from this 2 rooted package just offering a lot of stuff. Look at the single sculpted figure packaging for this. It's the size of a normal Hot Toys. Now imagine it duplicated for the second body/outfit + the jail cell base having to be packaged somewhere + the two rooted sculpts + the jail cell bench. You end up with the same problem.
