Or my least favorite, able to destroy everything in an instance just by connecting the movie to reality: "Ah, they search for a killer? It's that guy, because there is no other reason to cast that role and pay the premium to have this person also talk!"

Most blatant example: "The Bone Collector"

I don't even remember the turns of the story in that movie, as it was clear within the first 10 minutes...

i always appreciate a bone collector reference. what a ridiculous silly amazing movie.

for me the quintessential example is "Phone Booth." starring Kiefer Sutherland, you say? i wonder what role he plays.

i think the movie "Seven" (Se7en) managed to keep the surprise bad guy out of the trailer and unbilled until the end credits. that was badass.

That would be almost every movie and tv show ever for me. My wife is much better than me at figuring out whodunnit, but I can see stuff like this easily. Fortunately it rarely gets in the way of enjoying things.

I wonder what the bad guy in Se7en would do to someone like Kevin Spacey

I experienced what seemed to be a variation of this in Amsterdam, a David Russel film no less. Everything is revealed at the end but a character is tasked with verbally and lengthily repeating everything that just happened as if the audienced hadn't just witnessed it themselves. I was taken aback by sheer idiocy of the segment that it seemed like a caricature of a studio exec finding a very basic plot confusing and taking the final cut from the director and adding a ELI5 scene at the end.
