At least they set up a promising Season 3, at the end of Season 2, with those filmic tributes to "The Godfather." I say promising because the Luke Cage blandness problem may be resolved next Season, although they really need to find some weaknesses to his invulnerability, because he is just NEVER in any believable jeopardy.
I agree that Bushmaster was solid gold, and while he did indeed appear somewhat wasted, a set-up that never paid off, I anticipate that the payoff may come in Season 3, or maybe in one of the other MCU TV Shows.
Sweet Christmas, I hope he returns. And while it's true that I'd like to see Bushmaster return, I confess I never thought to say "Sweeeeet Christmas!" until you mentioned how much you hated it lol. ;)
