Question: So let me get this straight. After reading the questions and answers, and scratching my head for a while, I concluded this, after the corruption occurs and the jet engine enters it. The universes unravel because of the corruption. So to fix it these "time travelers" decide to give a reason for the engine to fall through the wormhole by making Donnie send it through, thus fixing the corruption. Is this even on track? I saw somebody say something cause and effect. So could this be simplified by saying they made it have a cause for the effect or vice versa in their universe to save it? I feel like there has to be some kind of time always has a flow and can't be interrupted kind of thing, but I'm really not smart enough to adequately understand that. Somebody also mentioned something about the events had to happen a certain way or they didn't happen at all. I may have misinterpreted what the person meant by that, but I would like to share my take on that. It's funny cause the only credibility to that is the film portrays the characters reacting oddly at the end (you know what instances I'm referring to). However, if this wouldn't happen then it would open up an infinitely large door of possibilities. Events like in this movie could occur everyday, but we don't remember. I could imagine, tons of scenarios and they all be credible and unprovable either way. I think it would have been cool to go in that direction cause you could have an infinite number of different Donnie Darko movies, but that's just my thoughts. If you get what I'm trying to say here. It's weird to think about cause it seems there's no purpose to think like that, but is there a purpose if your thinking about it in the first place? What is that purpose, that is the real question? I apologize in advance if this is too lengthy.
Question: I don't recall Gretchen ever meeting Rose, yet they seem to recognise each other at the end. Is it implied that they had met in the TU?
Question: It isn't that important to the plot but what does the back of the bus say? The second word looks like "rules" but I can't distinguish the "M" word.
Question: Two questions I had about the cellar at the end. What was the point of Donnie and his friends going to the cellar towards the end? Was he looking for something in particular? And the second thing was why were those bullies from school there at the same time? Did it have something to do with the story told in the film about how kids would try to steal stuff from Sparrow's house?
Question: Why was the universe ending? I have watched the movie several times and I cannot find an explanation.
Question: why was it the end of the world? what caused it to be the end of the world, and why did it change simply because donnie changed it so he died when he should have? how did the actions caused by him being alive amount to the end of the world?
Question: What was the whole point of the girls doing that dance number at the show?
Question: After Donnie has gone back to the start of the loop, he lets himself be hit by the jet engine, presumably to save Gretchen, Frank and everyone else whose life he screwed up in the alternate future. What I don't understand is, since he knows what's going to happen and can see the path (literally) in front of him, why doesn't he try to change it? If he knew what was coming he could save Gretchen without dying himself.
Question: What is the ending actually about. I think that when the plane engine goes through Donnies room, he dies and the rest of the film is him in a time loop seeing what would have happened but didn't because he died. Frank and most of the characters are vague memories from the last loop, kind of like de-ja-vu, but i'm not sure, so could someone tell me what the actual story is?
