Yeah, I’m someone who is very-pro kiss. I think it needs to be kept for several reasons.

1.) Every SW trilogy has had the space kiss.
2.) It wraps up the Kylo(Ben)/Rey story that began in TFA when he asked “What girl?” and then later carried her onto his ship, continued through their Force bond in TLJ, and followed through in “I wanted to take Ben’s hand” in this film.
3.) Based on the Kylo Ren comics, the novel/stories that feature his childhood, anything we know about him from other media/information, and from the films themselves, this guy has experienced very little happiness in his life. Come on, you’re really gonna take away these few moments of happiness? You’re gonna take away when he gets to kiss the girl?
4.) Carrie Fisher promised Daisy Ridley she would get her space kiss! Why you wanna take that away?
5.) Finally, as JJB said, we get the reversal of Anakin/Padme with Kylo(Ben) actually achieving what he said he wanted to do: Finish what his grandfather started. Anakin’s goal was to save Padme, the woman he loved. He failed. Ben does it. He succeeds in saving the woman he loves.

For all of the above reasons, yeah, the kiss between Ben and Rey absolutely should stay.
