Death Note for sure is great. Darker Than Black is great but it's too bad there's no complete series set. I also hate when they have these kinds of packaging. I love Cowboy Bebop but I think it deserves a reboot anime like a bunch of older animes are getting; the same for Outlaw Star. Trigun! YES! The only con is using thin pack cases.
Death note is always a plus imo . My new favorites are Shirobako Blu Ray by sentai filmworks, Evangelion 3.0 1.11 , Sailor Moon S complete Blu Ray by Viz Media ( preparing for the sailor moon cosmos movies ) and the Gundam Seed Destiny Remastered Blu Ray ( bundled with stargazer OVAs and ocean group Canada dubcast) .
Blu rays are very hard to scratch to the point of causing issues with the disc. The format you really have to worry about is DVD and 4k. I really hate that the new 4k format is so fragile, any small place can cause an issue. Be very careful with sets like that when we eventually move into 4k anime sets.
Next time I vote for an aerial video of your new drone showing the boxsets lined up! :) Still waiting on Crunchyroll to ship out that Cowboy Bebop for me.
