Myself, I still find Richard Donner’s edit of Superman 2 to be an amazing comic book film, and the best(certainly from a thematic point of view, but also in terms of the action and acting… sadly not so the editing, which was naturally compromised). I still love how the film’s climax is essentially a battle of pure wits at the Fortress of Solitude, with none of the sillyness of Lester’s theatrical version. And Marlon Brando’s restored scenes, almost 20 extra minutes worth, are brilliant(especially the moment he “physically materializes” in front of a surprised Clark in the scene were Supes gets his powers back), finally making sense of his $10 million dollar record paycheck.
I know I probably shouldn’t have, but frankly I also enjoyed the little additions that made the 3 villians seem much nastier, such as Zod’s amusement at brandishing of an AK-47(in the Whitehouse sequence) despite having superpowers.
I still think most great Superhero films owe their basic plot, characters and themes to it(looking accusingly in the direction of The Avengers right now).
It really does feel finally like the real “Part 2” and climax of the wider “Superman” story(which was actually written as 1 epic film screenplay that eventually they originally decided to split into two parts while they were filming it).
