Uh, I don't think it works that way. You have to start right at the beginning, to understand the journey of the characters. There's nice development for everyone. I only wanted to check it out and ended up watching six episodes at once (since they are only 20 minutes long). It grabbed me right in the first episode, when Galavant, big hero, strode into the church to rescue the poor damsel in distress who was about to marry the much older king, and she hesitated and said "Well, actually..."

That was when I realized that all the usual clichés would be turned upside down and you go in having no idea what to expect which makes it very refreshing. And everyone's so likeable.

And the lyrics to the songs are quite unusual as well. I think it was in episode 3 where Galavant and Isabella sing a very different love duet.

Really, just start right at minute 1 at episode 1. If you don't have a catchy tune three minutes in, then you must be dead ;)
