Well I didn't expect this... I know Matt Groening is creating a medieval show but I don't really know if this was promotion for this or the writers just wanted to reference Game of Thrones. Anyway this episode is just all over the place. So the Simpsons are in a medieval fantasy. I'm sorry is this Treehosue of Horror? So the jokes in this episode were only for people who understand Game of Thrones obviously. Marge's mother gets cursed and is about to be frozen to death so it's up to Lisa to save her with her "magical" powers. God, this episode was just unbelievable. This does not belong on the Simpsons. This isnt Adventure Time! I mean really? What a great start to the season.
However, the only thing I like in this episode was the animation. They really put their effort and time into it because it is absolutely brilliant. It was so full of life and very Disney-esque in a sorta way. Other than that this episode was just terrible and so ridiculous.
