This applies to the field of work as well. Meaning, your boss orders you to show up for a full shift, you show up on time and are absolutely willing to work, and then your boss realizes he has no work for you, your boss has to pay you for a full shift even if you don't work at all.
Fun fact: German law has a concept named "default in acceptance", which postulates that if there is a "service for payment" contract, the party that should provide the service correctly offers their due service, and the party that should pay fails to accept the service within due time, the second party still has to pay the first party even if there was no service delivered.
I've experienced sleep paralysis with ghostly images and similar things in the past and can snap out of it through moving my fingers. I've definitely hallucinated before and members of both sides of the family have had similar experience, some suffered forms of mental instability in two cases schizophrenia.
Cue the flashback to Jonathan, reassuring a terrified child: "What you are is never as important as who you are." Cue Superman's response to Brainiac: "I already know who I am."*John Williams fanfare plays*
I don't think we even really need to see Krypton. I'd start with Clark growing up in Kansas, thinking he's normal, and follow him through the development of his powers. There've been enough alternate takes on Krypton that it could actually work as a mystery; is this the pre-Crisis utopia, the sterile science world, or the relic of a fallen empire? Brainiac was there, and he tempts Clark with the knowledge of what he really is.
First, a Krypton film, ending with baby Kal-El being found on Earth. Then Supe's early career film, establishing his values... and if Jonothan Kent needs to die, it happens because of something like a heart attack while Clark is savnig folks on the other side of the world. After we know Clark minimizes property damage and never kills, have Zod & Company show up and force him to make tough choices.
Man of Steel seems like someone came up with a Superman trilogy and then the execs said "We've got to catch up to Marvel, make it one film!". I don't mean that based on the film's actual pacing, but because various story beats make more sense to me if they weren't all squished together.
I've been wanting to write a Superman movie trilogy for years; "Man of Steel" (featuring a Terminator-like Brainiac) was going to be first, with "Last Son of Krypton" (featuring the Eradicator) as the sequel and "Man of Tomorrow" (in which Luthor makes his face-heel turn) as the conclusion. Thanks to Snyder I have to re-arrange my titles.
