Season 2 is actually very funny when you consider it from Dr. Julien's perspective.
You've spent years trapped a lighthouse, convinced you'll never see your son again, and then bam! Your son just shows up out of the blue, alongside a ragtag team of ninja apparently? And hes a ninja too now for some reason? And apparently hes some figure of prophecy, gifted with an elemental power that he may or may not have inherited from the strange old man who slept at your house for one night 20 years ago? And the other strange old man who took a peculiar interest in your son is here too??? And it turne out the second old man is actually the son of the guy who created the world?? And they came in on a pirate ship that can fly??? And then they save you from captivity, which is great, but then theyre also heading for a mystical island where they intend to fight an evil dark lord who wants to take over the world??? And then there's stone soldiers and an evil plasma blob that possesses the green child's dad, and then a four-headed dragon shows up? And then the green child's possessed dad turns into another dragon???? And then a dopey elvis impersonator shows up and uses a magic helmet to take control of those stone soldiers? And then your son gets overwhelmed with dark matter and turns evil for a bit but its okay because the green one turns gold and everything is fine now? And then the guy who was just a dragon two minutes ago pops out of nowhere as a whole dilf????
Say what you will about Dr. Julien, but he really just took all that chaos in stride and I respect that.
