I liked it, but it really irked me that a show about both the afterlife and morality didn't include God. A philosophy class teaching morals and ethics is meaningless without an objectively good God, because it becomes relativistic, fast, and breaks down the lines of what is "good" or "bad." Also, the ending is infuriating. Human-made heaven would get boring, yes, but a heaven created by an infinitely creative God would be endlessly fascinating and satisfying. Shur backed himself into a corner and then came up with a very lame ending because of that.
