I feel like the original trilogy had some humor at the expense of Stormtroopers.

“Open the blast doors! Open the blast doors! Close the blast doors! Close the blast doors!”

They were always kind of inept canon fodder, although they weren’t as explicitly mined for comedy as the Battle Droids in the prequels. I think the problem with a lot of the humor in the prequels is that it often made the pacing of the films come to a halt. George often didn’t know when to cut away. I don’t really have a problem with quick quips and gags as long as the movie doesn’t dwell on them. I get that it can be a fine line though.
