If I remember correctly, the US Bonus Features Blu-ray disc that we didn't get was due to licensing restrictions, most notably the Toonami related stuff.I'd genuinely take actual content over artboxes. I know AL's whole mission statement is high class physical releases in an increasingly digital age but given how far we are behind the US releases, to in turn lose out on content is very annoying as a longtime fan who has had many of these titles already on DVD for 15+ years.
I want to support and promote the UK releases. Especially as the way the national and global economy is going importing is becoming less feasible. But it's annoying to wait for a title like this and find out some interesting content from the US counterpart was cut, leaving us with 2 trailers. Art cards and booklets are nice but they shouldn't be THE extras in my opinion.
