Schmigadoon was an amazing premise for a show, with the absolute WORST execution from the writers. It was great for most of the first episode, and every single episode thereafter was utterly PAINFUL to endure.
Making a second season of this show is a huge mistake. Take the highlights -- the actors in this show were fantastic -- and put them all in an entirely new show instead.
You couldn't pay me to watch another episode of this. I made an account here just to say this show wasn't "underrated". It was rated quite low, and somehow was still overrated.
