Well, this was a nice recovery from "Bad Little Boy." This episode was the most recent to address Flame Princess and Finn's relationship and, it did a pretty good job. It picks up with Finn trying to change Flame Princess's alignment to good from evil, despite her father trying to keep her evil. So Finn decides to take Flame Princess into a dungeon so she could get interested in Finn's interests. However, she gets bored and does not find the enjoyment that Finn does at these tasks. Eventually, after Finn tells her to do what she likes, she starts burning things down and destroying things with fire.
It was a cute, well timed episode, intended on keeping the whole Finn/Flame Princess relationship relevant to the viewer. It was also interesting because it showed the whole conflict of personalities between Finn and Flame Princess.
In all, it was a good recovery from the episode with Fiona and Cake and thus is rated a 9.5/10
Final Rating: 9.5/10
Rating Compared to other Flame Princess episodes: 8.5/10
