I hope there will be a fan edit that cuts some of the excessive humor, but not all of it.
One that needs to go in my opinion is BB8’s AT-ST antics. How did it get in the cockpit?! That one needs to go, and so does Chewie’s porg eating scene.
I also also think Snoke’s death scene would work better if we didn’t see Luke’s lightsaber BEING turned, just that it WAS turned right after Snoke is impaled.
Which humor is seen as excessive is probably very personal. I would cut some humor, but I’m fine with the AT-ST and the porg eating. And you might be right about the Snoke scene, that’s something I will try to do and see how it feels.
