Magnolia is the first in this regard for me. You know, you expect the lives of such characters to intersect by coincidences or something, but it's not relevant. There is no plot, no fiction... On top of that, the movie is three hours long. They filled in good actors, there is no script, at least they said that acting should save it, and that wasn't enough either. I still don't know how I watched that movie for three hours. All I remember was the scene where frogs rained, and I didn't understand what the hell it was.
