As stated, any more of Tsuburaya's work would be great. Fireman, in particular, is one I have been dying to see. I feel with the show's more adult-oriented approach, it could do well. But I'd also love to see some of their other outputs like Mighty Jack (and its sequel Fight! Mighty Jack), Operation Mystery, 10-4-10-10, the Heisei Ultraseven specials and Ultra Q: Dark Fantasy (Especially with Neo Ultra Q online).
Toei's work is a whole other world, and there is so much to choose from, but some titles I would love to see include Robot Detective, Inazuman Flash, Akumaizer 3 (and its sequel Chojin Bibyun), JAKQ Dengekitai, Daitetsujin 17, Denziman, Flashman, Jiraiya, Jiban and B-Fighter.
There are so many other Tokusatsu shows out there, but just a few more titles include Silver Kamen (Perhaps most so after Fireman), Lion Maru, Zone Fighter (Though obtaining it through Toho could admittedly take some work), Mach Baron and Megaloman.
Thank you for all of the great programs already available and I cannot wait to see what else you guys have in store!
