If the question made no sense, then we wouldn't have 6 pages of coherent discussion about it. Which we do.
And let's break down Clark's overall live-action feature film career by whether it was a Big Success, Moderate Success, Moderate Failure, Big Failure.
1. SUPERMAN AND THE MOLE MEN (1951) pros: led to the mega-successful TV series also starring George Reeves. Cons: almost no one remembers that this was Clark's first feature film. Grade: Moderate success.
2. SUPERMAN: THE MOVIE. Pros: the big bang of the modern superhero feature film genre that set up much of the format. Cons: pace is agonizingly slow by today's standards. Grade: Big success.
3. SUPERMAN II. Pros: 1st super-powered onscreen fight. Cons: hodge-podge tone due to two directors with different styles, mind wipe kiss lacks consent. Grade: Big Success.
4. SUPERMAN III. Pros: uh, still top 5 commercial domestic films of 1983? Cons: terrible sfx and story. Grade: Moderate failure.
5. SUPERMAN IV - THE QUEST FOR PEACE. Pros: none. Cons: all. Grade: Big Failure.
6. SUPERMAN RETURNS. Pros: excellent plane rescue scene and bullet off the eye scenes. Cons: terrible costume, terrible Lois, wasted Lex, no action, deadbeat dad angle, ham-fisted aping of Donnerverse Supes. Grade: moderate failure.
7. MAN OF STEEL . Pros: most visually dynamic portrayal of the Superverse ever. Best fight scenes. Cons: Pa Kent. Neck-snap to learn neck-snaps are bad. Devisive AF to audiences. Grade: Moderate success.
8. BATMAN V. SUPERMAN - DAWN OF JUSTICE. Pros: uh, best Lois & Clark cinematic interaction. Clark clearly most heroic of these Trinity. Cons: literally everything else, basically guest star in his own sequel. Grade: moderate failure.
9. JUSTICE LEAGUE. Pros: most badass cinematic Supes ever. Bright and hopeful and powerful AF in battle. Cons: rest of movie sucked. Shrek-mouth. Grade: Big Failure.
Yup, Supes is way more hit or miss at the movies.
