I think that the ending to season 3 is a real cliff-hanger. It REALLY makes me want to run into Cartoon Network studios and watch all of the up coming episodes! I really didn't like all the sing-songy love stuff, but besides that it was really good. Beemo was SO FUNNY, "If anyone tries to hurt Finn, I WILL KILL THEM." LOL!!!!
All in all, it was really good. I can't wait to see more of Flame Princess (best character EVER, reminds me of myself)
