I've watched this movie many times and I still don't know what is happening Can you explain what's going on
Its a really long explanation but here's a link: http://www.donniedarko.org.uk/explanation/ Really good movie btw
Basically long story short "He is mad!" But still there's a very good explanation to all that shit which I found by Google sensei after watching the movie three times and still had some confusion. But yeah he is delusional. End of story.
To me, it was a movie like time travelling/alternate travelling in a parallel universe (he experienced an alternate existence/possibility and 'deleted' his own existence).
PS I think it was listed under movies you wouldn't watch more than once. I think it was on a list like that It was true for me since I only watched it once and it was enough
