WT..... F.... IS THIS ENDING?!

It started off with potential. Binged watch it and it started to drag from past the episode 25 Mark.
And the ending? What in the world is this ending? It just ruined a potentially good story.
I think the writers were trying to do something different for the ending but the result is appalling.
They need to be brought to the gallows.
I felt like I've just been cheated by pro scammers..
