I dunno thought it was a reasonably good payoff for what was a bit of an underwhelming season. There was an action packed showdown. Boba Fett firing knee rockets and riding a Rancor. Murdering a guy with his gaffi stick. Most of the plotlines arriving at conclusions. Definitely agree we could have seen one or two more of the scooter gang or Freetown people die in the fight that was apparently going so wrong for a lot of it. Bad guys vs good guys, ragtag group defeats sinister organization.
If you're looking for complex plot twists and deep intrigue in your story you might be looking in the wrong place. This is Star Wars, they literally just blow up a Death Star in like 60% of their movies.
It’s not a good payoff for most because they integrated the cartoon series into all the Disney + series across the board. That guy was a reoccurring character in that series. Not many people have seen it.
