We watched all 4. The first episode I wasn't so sure about, but I think it got better as they went. A bit raunchy at times (I have 13 and 16 year old girls, so I don't have to worry AS much as before, but still would prefer less of that...). We loved the song about love that they sang in the dungeon!
Last night after the finale DD13 was really blah and I asked her if it was about the way it ended (she really gets into movies and shows) and she said yes. Surprisingly she still thinks Madalena and Galavant should be a couple!?!
