Count me in as one of those who liked the Rathar scene! It’s not worthless since it: shows us that Rey is not infallible, saves Han and Chewie, gets Han and Chewie back into the Falcon and kind of forces him to take them to the Resistance. It also re-establishes the fact that Han is a shoot first, talk later kinda guy when he punches the henchman and throws him into the mouth of the beast. (Better him than me!) Perhaps it was JJ’s middle finger to Greedo shooting first?
I understand that it may have seemed a little Men in Black-ish, but I liked that it did something different than other large creature encounters we’ve seen in the other films.
