Amazing finale. Really enjoyed them pulling back and examining what was basically Jason Segel's career and his aspirations. Also loved the little touches like the cereal container from Forgetting Sarah Marshall. With the "The End" at the end, really feels like this is a one and done, which I'm fine with as far as the series telling its own story, but at the same time I do wish there was more time to spend in this world.
This could end up alongside Mr. Robot and Legion as far as trippy, strange shows that I can't help but get sucked into despite not understanding everything that happened.
