Re: Most obvious plot "twists" (spoilers)
One of my crowning achievements in life so far has been guessing that Willis was dead about 15 minutes before the climax of The Sixth Sense. I wouldn't call it an obvious twist at all, but I sniffed it out.
1989 - "That Batman movie was pretty good. I wish we had more comic movies..."
2015 - "Aunt May is too young, Aquaman isn't blonde, Apocalypse looks purple, and ALL THESE ACTORS ARE TOO SHORT! HOW COULD THEY DO THIS TO MEEEEE?!?"
