Definitely the Batman film series for these two:
As for Superman, eh...more than any of the big budgeted glitzy star-packed feature films of Superman by Donner, or Lester, or Singer, I prefer the first Superman feature film, called Superman and the Mole Men (1951). This low budget, black and white feature. It features a Superman that battles something other than Lex Luthor and Zod. This Superman battles against prejudice, ignorance and conformity of people in groups forming a lynch mob. I'm glad the film wasn't Superman versus the Mole Men, and instead was Superman defending the Mole Men with a still relevant moral message against discrimination and the closed minded group-think mob mentality. As George Carlin use to say, "Never underestimate the power of stupid people in large groups."
It features a feisty Lois Lane with attitude.
It also features a competent, serious Clark Kent that isn't a goofy bumbling buffoon played for laughs.
A Superman with an edge, outraged by the prejudice of the people. "I'm going to give you one last chance to stop acting like Nazi stormtroopers!"
Of course they're not swayed by Superman's words of reason, Superman disarms the lynch mob, "That shot came close to killing Miss Lane! Obviously none of you can be trusted with guns, so I'm going to take them away from you!" They try in vain to resist him.
It also has this Buick Roadmaster Convertible.
how the heck did the Penguin get the batmobile's blueprints, of all things?
The Penguin and the Red Triangle Gang obtaining those blue prints to the Batmobile is intended to be surprising, ambiguous and mysterious. It's intentionally left unexplained. How they actually did it is left open for interpretation. This isn't a mistake, it's intentionally unexplained in the film, to keep you guessing. If you enjoy some mystery, allowing you to use you're imagination, then you can be intrigued this, but if you want everything spoon fed and explained to you upfront without requiring any thought of you're own, then this will just annoy you. Not knowing the specific details of the back-story on the Penguin and the Red Triangle Gang obtaining those blue prints never bothered me one bit.
Tim Burton states his viewpoint in his commentary, "That kind of not knowing makes it more interesting."
Batman Returns screenwriter Daniel Waters did broadly explain about the Penguin, "Penguin is a character that evolved in interesting ways. When I came up with something in the script that he takes documents that have been shredded, and goes and painstakingly glues them together. That suddenly unleashed a lot in Tim of the guy underground, and he's taking all our crap, but he's doing something with it, and he knows our secrets."
