Probably the two a half billion people claiming to identify as christian while actively opposing and taking action against any of Christ's non-self-serving ideals.

The details around the assassination of Archduke Ferdinand really jump the shark. Must've been a drug-fueled writing session on that one

That DB Cooper storyline was never resolved.

The fact the Pepsi at one point had the 6th largest military in the world, and did nothing to conquer Coca-Cola.

Like, why even start that storyline if you dont take it to the inevitable conclusion?

Are we supposed to believe the largest most dominant military force in the world, Kublai Kahn's Mongol fleet was defeated by some inclement weather... TWICE?? Lazy writing.

The whole wrapping up world war 2 using "the gadget" just reeks of writers struggling to wrap up after writing themselves into a corner.

A few Prime Ministers have been peculiar plotholes. Harold Holt just disappeared. Whitlam got taken out by a madman influenced by the yanks and nominally working for the Queen. Sometimes it seems the writers just get bored of the storyline and drop stuff.

That there wasn't a single mainstream Republican who stood up to Trump during his presidency.

I mean, come on. Who wrote this?

We're supposed to believe that EVERY SINGLE REPUBLICAN in government went from taking about how unfit Trump was when he was a candidate ... to standing behind him 100% even when he cozied up to Russia, paid hush money to a porn star, and lied about a Presidential election?

I don't know about this series, but I play a game with the same name and absolutely hate it. It's hugely pay to win with permadeath and the grind has nowhere near the payoff for the amount of effort you put in.

Probably the stars that are older than the universe.

Nobody has figured out who the Zodiac killer is yet? Come on, people!

Just to emphasise:

from 1990 and before

What did drugs ever do to start a war???

The universe is not locally real*.

*Locality and reality are defined in specific ways within quantum physics, and "not locally real" doesn't necessarily mean 'illusory' as you might expect. Look into it, it's some crazy shit.

If most people are good why doesn't the world get better without violence?

The Space Race ended without closing ceremonies.

That one on 25th Street that I hit the other day. Oh wait, you said "plot". Nevermind.

The Trump storyline is taking way too long to reach a definitive conclusion, and I’m not even confident that it will be a particularly satisfying one.

The popularity of Harry Styles

The low entropy of the past

Where all the aliens are.

Hard problem of consciousness

We experience first-person sensations (consciousness/qualia) and it's a big mystery what's up with that.

Jet fuel can't melt steel beams 😔

Edit - too soon?

Id argue the last season ended with the US withdrawal from Afghanistan, if the season started with 9/11.
