When i first watched the preview of this episode I felt that Charlie's 'peons' joke felt very forced. It felt like zach saying a joke instead of it being something Charlie said, I dismissed this though as a small miss. I had a similar feeling with the whole 'i don't get involved with politics' *boss comes in* 'guess who just got a call from the president' joke, but once again dismissed the forced nature of it as a critique of that cliché. But throughout the rest of the episode i kept noticing this forced feeling, specifically with charlie/zachs lines. Zach is usually an incredible writer and voice actor so the nature of his lines makes me somewhat doubt he wrote them.
This episode also suffered immensely from the 10 minute run time, and felt so fast paced I got a headache.
Other than that I don't think it was awful. A standout part for me being Pims ark. But it was definitely the weakest episode so far, and when I inevitably rewatch the series for the 100th time I will probably skip over it.
