The overacting and hamming it up was hilarious. I think it was intentional.
When they kicked him into the empty cell and all hooted and laughed it was straight out of the 60s Batman show, it was so over-the-top.
Agreed. The campy-ness was definitely intended. They all still felt like they existed in a star wars universe. Even Bill Burr! Who I thought was gunna play a much smaller cameo role. Humor was great in this episode and as someone who has always been a fan of "putting together a team..." heist type scenarios, I loved it.
