My understanding of donnie darko. There is a gltch in the universe. It splits into two alternating universes. One where everyone is robots or corrupted versions of the real world and one where everyone is very sad and snippy because they know that thr two universes must be resolved and the events in it must be completely erased. Frank is there to ease the wormhole which is created to stitch the trimmed parts of time together. It keeps flipping back and forth between the two competing universes until they can get an airplane engine fall together (thats the high velocity way to make that time portal. Theyre using time travel as a way to erase parts of time. Donnie is the only person that can see frank and understands that there are two universes. The snippiness shows when theyre like 'this conversation never happened' they know theyre screwed. When donnie pushes against the fourth wall to talk to frank thats him pushing against the opposite universe. Therapist talks about donnie's inabilist to "deal with the forces in the world that he deems threatening." He uses the knife to try to break the wall get to frank and stops the universe from being destroyed. Frank flashes his eyes to make something happen. That causes his parents to prescribe more medication so donnie can join everyone else in not being aware of the parallel universe. Frank is a construction of glitches in the universe. Random ideas combine together (frank, the rabbit, multiple voices)- maybe theyre pulled from the more agitated moments in the a universe (like when he calls out the motivational speaker). He starts being able to see his "destiny manifest itself visually" when his soul is sent. The teacher is another time traveler (as is frank) "im not going to be able to continue this conversation... because i could lose my job" AS A TIME TRAVELER WHO THINKS"darkness is part of a natural progression" so at this point everyone is like oh god we have a few moments left for our universe to live lets find love and happiness and shit which is why donnie is getting it with that girl. Frank "why are you wearing that stupid mansuit" yoooo he says it in a different voice. Whoaaa have you ever seen a portal this physical movie is the way they are creating the wormhole. When the opera singing starts is when the engine is starting to fall and stitch apart the universe resolving things. Holy hot damn i am high
