I think the topic title is interesting “the ending was very easy to predict.” Sure, all the clues were right out there in front of you to predict… but did you? I knew something was up the moment we saw him (the hair) but I wasn’t able to figure out what exactly until the film revealed itself. The closest I got was when Kylo finally sliced through him (my thought - did he die already and now he’s a force ghost?), but when the real trick was revealed it was definitely a “holy shit” moment. And of course that’s what it was, a magic trick, and like the best magic tricks it occurred in plain sight.
