- Awesome Music: The heroic and bombastic opening theme. A pity it's pretty short.
- Cry for the Devil: It's hard not to pity Lord Harwood (the show's Big Bad, of all people) a little between the moment he gets tortured, mutilated and brainwashed by the Barbers and the moment Bet Sykes finds him when he's a helpless hobo in the streets.
- Hilarious in Hindsight:
- A major part of the plot in Teen Titans Go! To the Movies is the studio's apparent willingness to give every other DC Comics character or team a movie of their own over the Teen Titans, and Alfred Pennyworth was one such character mentioned to be getting their own movie. Pennyworth was announced between the production and release of that film.
- The second season of another DC Comics-inspired prequel series, Krypton, ended a few weeks before Pennyworth started. In it, the protagonist (who's part of Superman's family) goes up against the dictatorship that rules his home city and world at large after taking over it during a coup, then eventually puts down said dictatorship. Alfred (who serves Batman's family) does the same in his home city and country.
- Like You Would Really Do It: Thomas Wayne gets severely wounded by gunshot. Everyone and their grandma knows this is not yet his (and Martha's) Death by Origin Story moment for Bruce/Batman. Sure enough, Martha revives him.
- Older Than They Think:
- Some people believe that Alfred's backstory is being "spiced up" to keep it from just being about a normal guy. While some liberties are obviously being taken, Alfred actually did have a military and espionage background in the comics and some previous depictions in other media (his Michael Caine incarnation in The Dark Knight Trilogy famously talked a bit about it for instance, and the fact that Jack Bannon's acting in the series emulates Caine is no coincidence), including Gotham.
- Thomas Wayne having a sister isn't completely out of the blue. He had a sister named Agatha who was on Earth 2 prior to 1986's Crisis on Infinite Earths. She appeared in 1955's Batman #89. Her canonicity these days is a bit suspect but she appeared very briefly in the fairly recent Grant Morrison's Batman. Bruce also has three uncles, albeit on his mother's side, so the idea of him having an extended family isn't entirely out of nowhere.
- Unexpected Character: The fact that Alfred, of all people in the Batman franchise or even in the whole DCU, was getting his own television series got this reaction from many.
YMMV / Pennyworth
