It was completely rushed. All this time setting a mood and a slow, yet eventful crawl to the bad guy. It was way too easyto tell who the big baddie was as well - way too easy.
Then in the end, it was a mess, pushing itself far too fast. One of them, if not both, should've died. It's a cop out to have them both live and become (supposed) best friends. They were literally laughing with this long slow pan up to the stars - very, very weak. For what the show was lining up, it was way too "happily ever after".
A real letdown from how the rest of the show was.
