This was originally supposed to be the series finale, and a fitting one it would not have been. While funny, it did not feel like a momentous occasion. I am all for the mindset that a finale should be just a regular episode, but it has to be a classic, not this.
This was probably the very best Spence and Danny storyline of the season though. "We've been talking all night!" Great back and forth between the two, who should be getting more work than they are.
And the ending with Doug bringing Arthur back was a nice, emotional moment for the comedy-heavy show.
