I just finished it earlier this week and I really, really liked it but I am completely undecided about that ending, totally not what I was expecting. Some highlights for me are the multiple transformations of Huey, the amazing baby scene, the dolphin and lobster scenes others mentioned and "The Female"'s part in the confrontation with A-Train in Huey's house. Some seriously dark-ass moments along the way that really blew me away like the hijacking and the shooter in the building.
Can't wait to see where they take this next season.
