Gundam. DBZ. Naruto. And ideally a decent chunk of that budget would go towards a showrunner who actually understands the emotional heart of the source material and we'll finally get a good live action anime adaptation

It's been a minute since I've read, but I remember being similarly impressed with Trigun Maximum as I was with the Fullmetal Alchemist manga. There are a lot of similar well addressed themes of purpose, sacrafice, redemption, and manipulative world ending threats from things/abilities that were supposed to be humanities salvation. I know the community is very biased, and the FMA manga remains probably my favorite, or if not - 1a, b, or c...but Trigun Maximum ranks up there as well imo.

Don't let the charming but rushed quirkiness of the original anime fool you.

EDIT: this series does not look manga accurate though so oh well. Would have loved to see a manga accurate Angle Arms fight finally adapted for animation
