Half of the humor had this smartass self aware vibe to that rubbed many people the wrong way. I think they were trying to imitate the OT style of humor, but it felt more like the MCU and Joss Whedon school of comedy, which is becoming dated and repetitive from a decade of overexposure.
The other half was BB-8 slapstick and Finn being a clown. I didn’t mind most of the BB-8 comedy, but I don’t think Finn’s dialogue should be as lighthearted, considering his backstory and character arc is pretty serious.
I personally think maybe about a third of the jokes in the Sequels landed. That’s certainly better than the Prequels (unless you retroactively count the dozens of quotes that have become memes), but the ANH, TESB and even Solo do it better imo.
