The ending to Donnie Darko ruined the whole film

It was so cool up until the ending. That was some of the most pretentious garbage I had ever seen. People praise this movie and act like they’re super intelligent like they perfectly understood that complete nonsense. The movie was so good and dramatic up until they ruined it, too. So many cool moments. Instead I have to scroll YouTube to even attempt to understand what they meant by using that ending, but it’s all a waste of time because the writers probably don’t even know either. Pretentious garbage.
