Alright, let me elaborate more on my review from YT on the flaws of this episode:
The plot(which I briefly mentioned as one of the things wrong with the episode) was pretty simplistic, predictable and nothing special, really. Given the fact that anything could happen in a cartoon universe such as this one, there are many ways you could've at least twisted the plot to make it feel less like a children's cardboard book, especially since you got Dan, the logic twisting fourth-wall-abusing nut-job as the main focus(and the build up you had with PD coming to life and all). Think about the ways the scenario could go in your world, write them down, take out all the unnecessary details and choose the best most unexpected option instead of slapping your characters on a formulaic concept with little or no change at all and just going along with it.
I know people have been complaining about how underwhelming the voice acting is, and I agree to that, but instead of talking about the whole cast, I'll focus more on Gerardo's performance on Dan since he has the most lines in this episode. I get that he's supposed to give off the "energetic wacky" vibe, but the way he tries to go from one emotion to an extreme other comes off as more of a "yelling in a loud environment to get your attention" feeling instead. Gerardo, your a cool dude and all, but pleas try to practice and experiment some more on the tone without it going too "S1 monotonous" nor "S2 Constant Screaming Mode". Even the extreme needs its restraints. (I'm aware of the fact that some of his lines are re-recorded, but that doesn't change anything for the better)
LIke I said before, its not too bad, but could've been better, which isn't a surprise considering how MMM went, so I never really got my hopes up for it in the first place. I know, it sounds pretty harsh, but I'm only doing this because I see potential in your work, and I want you to grow as a great cartoonist.
