It can be both. It's a lazy bit of writing, but it's still Anakin Skywalker's redeeming moment. Palpatine surviving doesn't change the fact that Anakin made a "good" choice to sacrifice himself to save Luke. I think having different writers just made for a disjointed trilogy. Snoke wasn't an interesting villain, and Rian Johnson tried to make Kylo Ren the big-bad by killing off the uninteresting villain (snoke) That left JJ Abrams with the choice of either keeping Kylo Ren as the big-bad, or giving him a redemption arc, and introducing a new big-bad, which isn't a great idea for the third act of a story, or re-using palpatine. Also not a great idea. If Palpatine was going to be re-used, it should have been hinted at in either 7 or 8, which is why I don't buy for a second that this was planned out from the start. I think ultimately the problems they had is that RJ and JJ just wanted to take the franchise/story in two very different directions, thematically. I could have seen going with different directions for each episode, but different writers for each left us with what we have, which is stories that don't really feel connected. When I watched this movie, it kind of felt like it was trying to be a sequel to 7 instead of 8, while carefully admitting that the events of 8 actually happened. It is what it is, I enjoyed the movie quite a bit. Maybe with multiple viewings I'll be more critical. Probably will be. Plot holes and story elements that don't make sense show up more the more you view a movie but my first impression was simply that it was a fun popcorn movie that felt very "Star-Warsy". Here's hoping Disney learns from their mistakes and successes and moves forward and gives us some new, good Star Wars stories in the near future.
