It's certainly a matter of opinion. Things like Luke's rejection of the Saber and his life on Achto being played for laughs just seemed kind of out of sync with the tone of that story arc, like they wanted to squeeze in some laughs before establishing the past tragedy. Same with the prank call and Hux turning into a spineless idiot for no real apparent reason. The humor in all of these cases felt (to me anyways) manufactured to fill a laugh quota rather than arising naturally from a situation as was the case with, say, Han verbally flailing to keep the situation under control in ANH, Yoda's testing of Luke's patience and intentions in ESB or C3P0's constant slick-witted cowardice.
Rogue One had a similar problem, but hid it better through characters who served little other purpose in the plot than to deliver the humor. Still, lines like Vader's awful pun don't feel like anything approaching a natural inclusion in the script.
