Tales from the borderland worked because it was full of twists and betrayal, but at the end you just pick the pieces up and put them in a trash compactor.
The stuff with handsome Jack was pretty cool. But at the end it became just two linear. It’s was like “Let’s gather our friends and kill the Monster” and then they gathered their friends and killed it. And what an unexpected surprise: It didn’t work out as planned and then someone had to sacrifice him.
And they have totally overdone this friendship-thing. It was simply too positive and too nice. The ending was like claptrap and everyone within the borderlands series hates claptrap.
