Because Breaking BAd and The Sopranos are the better character drama.

Honestly, I hoped LOST took the Twin Peaks: The Return road. My complaint is not that they didn't explain. My complaint is that they were obsessed with explaining things like the mythos and lore.

As soon as the show focused on the exact mechanisms and secrets of the island--the core of the last few seasons hinged on this spring of life garbage--while putting the characters in the back, I stopped caring. Then introducing concepts like time travel or characters having some kind of secret origin or someone is a destined hero or something...

The Abrams mystery box gets used as an example of lazy writing but there is a point behind it: some things are better off unexplained. Answers don't stick with people the same way questions do. Random bullshit with no feasible answers doesn't make an interesting story, but not everything has to be explained to death, especially when you are tackling supernatural speculative fiction.

There’s a difference between a mystery where answers were promised (Star Wars Sequels, Westworld) and one where it’s intended to remain a mystery (the unknowable horror of Lovecraft, G-Man). The island used to be an entity outside our understanding, but it connected and revealed about the characters to create a human drama like Solaris.

It is the same reason why Silent Hill 2 is considered the best installment because it doesn't really focus on the town. Then its sequels dissect evey single detail about Silent Hill. Origin had the player literally stood in the room as Allesa burned because people want every answer fed to them. Homecoming was no longer about a human story, but a freak show in a spooky town.

I still love the first three seasons of LOST. I love the characters. The character-centric episodes like the ones with Lorke are some of the best written TV. The mysteries it raised are on a more smaller scale. Then the show throws in batshit insane concepts and fantasy nonsense like gimmicks, and then answers every single one of them in the most boring way possible.
