Major Mando Spoilers! (I ain’t tagging though!)
I didn’t mind the Luke bit. Loved it in fact. I think if the characters had achieved little up to that point in the episode, it would have bothered me. For example, when Ahsoka turned up in an earlier episode, it really showcased how tough she was (a good thing in itself) but Mando did very little that episode.
Likewise when Fett and Shand turned up and were really tough hard-cases, Mando spent a good potion of that time unconscious!
Now I like those characters, and I enjoyed the episodes overall and I even enjoyed how tough they were. I get that they wanted to showcase those characters (spin-off central) but it bugged me a bit how sidelined and ineffectual Mando seemed as a result.
In this last episode though, Mando single handedly takes out a dark trooper, by himself (a major feat considering how tough those things were shown to be) and then defeats Moff Gideon who is wielding a lightsaber… with a spear. It’s a tough spear made out of near indestructible metal, but…. point is he’d achieved so much by the time Luke turned up to save the day. I guess it felt earned somehow, so Luke’s bit didn’t bother me.
That being said, if Windu had turned up instead, that would have been really cool, and I understand why oversaturation of Skywalker could be an issue. I don’t think we’re there yet in these series, though.
