Alright, I'll take he bait, if only because I have more to say than "How stupid":
1: If Luke turned into an actual villain, that would be unexpected. But he doesn't, it's just the usual "Grizzled veteran apathetic about saving the world until some kid gives him motivation" thing. That's not a change, that's just a time-out from him being his regular self.
2: The whole reason why Rey's parents were a big issue was because the movies portrayed them as such. I GUESS red herrings can count as unexpected, but it's not the good kind of unexpected - because if the movie wasn't setting it up, "Rey's parents are nobodies" would not be unexpected at all.
3: Force-sensitive clones would be cool. Also cool: not having those lame-ass characters. Wanting something cool is not a sin.
4: Not giving the big bad overseer a backstory is just bad writing, period. Like, it could work if he was always behind the scenes, in a "live in the shadows, die in the shadows" way, but Snoke was front and center for a whole lot of the two movies. It's just that none of the characters decided to fill us in on who he was.
5: Han surviving would be legitimately cool. I mean it, there's so many directions you could take to make that work, and they're all interesting.
6: And finally - and most obviously - people LIKE comfort and predictability. Nobody watches an Iron Man movie going "I sure hope he turns into a drunkard in this one" or "Wouldn't it be great if he died before saving the world?". There ARE times where you go against the norm, but it has to be because you have an idea that only works as such; being contrarian for the sake of being contrarian is not, by any metric, a good thing.
