I don't mind a remake presenting the ending that we've come to love, or changing it for the better. FF7 remake fukked up on two things, literally making it about time shenangians and changing the ending.....for the worst. Some times its best to do the Resident Evil, give me the ending I know of, and present side stories/more backstory on characters people like (Ada Wong).
And Mushroom Samba, yes. An episode that's lost on a lot of fans to begin with. A lot of the watchers think its just a throwaway filler* episode, but it pretty much gives us the blueprint for each character; from Spike endlessly walking up stairs, to finally stop at the top of the Bebop, makes perfect sense, he's the mascot, who will relentlessly "climb" even if it means risking his own life, to Jet finally finding his peace in cutting bonsai's, which is the complete opposite of his character, patient, precise and freestyle. Such a beautiful episode both with Django and Gungrave references. Its gonna be lost in the live action.
Again, Altered Carbon and Firefly did it better.
