My question, in all seriousness, DMcG, is, why did you even watch that movie? It obviously wasn't your kind of movie, and, it was obvious what kind of movie it was. Why do you think that that particular movie should "Challenge the audience"?

There are plenty of movies that challenge the audience. Watch "Tree of Life" or "Melancholia" if you want movies that are visually stimulating and intellectually challenging. Instead of spending your timing complaining about the movie that you didn't like(the top grossing film of all time), spend the time looking for films that are
more engaging.

Only thing, if you want to be challenged, don't expect to like the film, it will probably get you upset. That's why we call it "challenging"...
