But if Ben Solo and ST elements are going to ruin your enjoyment, I think you might want to stop watching right now. I say that with all sincerity of caution because I see it now as highly likely that a bridge to the ST is being built here. Luke gave Grogu a choice between continued attachment/family and a higher selfless calling. I don't think the contrast with Ben Solo's eventual choice and circumstances is merely coincidental.
My guess is that Luke would gladly watch Grogu choose family (Din) instead of the Jedi life, and might end up doing exactly that. Luke understands the demands and sacrifices of a Jedi path, and that no student should continue down that road if their heart is conflicted. That's going to be why Luke was so hard on himself and despondent after Ben Solo became Kylo Ren. He says as much in TLJ when telling Rey about his hubris and believing he could succeed where his mentors failed. He likely blames himself for keeping Ben with him and not acknowledging how much it would potentially mess with Ben to feel neglected by his parents and bitter toward Luke for playing a role in that.
