Cowboy Bebop. Let it rest in peace.
I wanted more for years but I've since come to the realization that enough time has passed that they could never replicate the look of the original, it'd look too clean and digital and consequently would lose a lot of it's "feel"
That and it really did tell a complete story more or less, which more animes should be willing to do instead of the default "Maybe we'll get to do more?" endings.
The only thing that bothers me is I do feel they did my girl Faye Valentine dirty by leaving her fate up in the air, I do wonder whatever happened to that character, I can see potential in doing a series where's she's the main character, a sort of "Chronicles of Faye" if you will.
The setting itself of Bebop is also an interesting one and I can also see potential in using that setting again but with a new cast of characters, a "Cowboy Bebop: The Next Generation" if you will.
But in both cases you run into the issue with the animation, it's really too bad nothing looks like anime sometimes did in the late 90s anymore.
Sometimes it's probably best to just leave these things well enough alone, otherwise you might wind up with an Eureka Seven AO, which ruined Eureka Seven's happy ending.
The older Cartoon Network shows they haven't ruined yet (i.e., Dexter's Laboratory; Johnny Bravo; Ed, Edd, n' Eddy; etc.). They've already ruined PPG once and they're about to ruin it again.
The only potential I see in bringing back old Cartoon Network stuff is if they did Adult Swim spoofs much like Adult Swim spoofed Hanna Barbera shows, that might be funny, otherwise it should be left well enough alone.
