The Hand has been a failed experiment from the get-go. Count your losses Marvel.
They're not interesting, they're barely threatening, everything they've been doing up until now has been constantly cryptic and poorly explained. It doesn't make them mysterious, it makes them a dull confusing waste of time.
It's been three shows. 34 f-cking hours of screen time and I still do not know what their basic motivations and goals are. Defenders came close, but even when Stick described their Lucifer-esque backstory and I thought, finally, these Hand fuckers make sense, it still left me with a ton of questions. Why did they invade and destroy Kun-Lun if they consider it their home? Do they want to get back to Kun-Lun or make the Earth a land of immortal men? If they're running low on the black goo than why'd waste the remains on Elektra? Because their leader has a hard on for her? Why does this arbitrary f-cking monicer make her the ultimate means to the end? What is a Black Sky?
Ooooh wait. It turns out they've been trying to get through this door that leads them to a dead dragon that they discovered while Goa somehow created an earthquake because the goo is in their bones and the dragon for some reason left Kunlun, died and is now pillars new york.....now it all makes sense!
Wait, why didn't they just find a way to get around the door......aw fuck it!
STOP Marvel. If you're having this much trouble just making a villain make any sense after three shows, you've failed with them. Get rid of them. I never want to see them again, I don't want to hear the word hand uttered. They suck.
Why not have Defenders fight some street level faction of Hydra?
