It wasn't a bad ending? Not a great or exciting ending. Lots of exploding spaceships that I really didn't care much about. But some good stuff in there too. Never figured out why "the Serpent" was included and even why Kate Stewart was included. But then again The Division also just kind of vanished and didn't seem like it had much of a payoff.
Spent the last 5 minutes just hoping that the god-like villain behind the villains would not be Omega. So much anti-matter nonsense had me afraid that they'd try and shoehorn in yet another "fan favorite".
Lots of setup, but kind of fizzled out at the end. Nothing too cringe-worthy like many other finales. A solid 5/10.
