Okay, let's see here. I rarely DON'T understand a movie. Maybe in that light, I would be good as a film major. I am incredibly open-minded, perhaps too much so sometimes, and I read into everything and try to see all sides.
Now, sometimes I don't understand why the heck someone found the inspiration to even put a movie out. Like, let's say, the Strangers. Seriously? No plot WHATSOEVER. I just hated it.
I don't think the Happening was BAD. I wouldn't pay to see it in theaters. It takes a different level of thought to appreciate the movie, and I just kind of felt amused at the end. This is a spoiler, but it's about global warming... they never come out and say it, but it's obvious Shyamalan was trying to make a statement about the way we as a world neglect the planet's needs.
I've seen so many movies... it's hard to remember what I was a little confused about or just plain didn't like.
Ah! A Cinderella Story? Ha! Come on, now. All these high school type movies had a surge of power, but it was just too much. Same message over and over, and most of the later ones to come held no new concepts or anything.
I don't get angry when people don't understand, though. A lot of directors have taken the route where they stand for their beliefs in a weird way through a complicated story. Like, Land of the Living Dead, where the director was trying to make a statement of the homeless situation in our nation.
The only time I ever got angry was when my friends said Pirates 3 was stupid. A movie isn't stupid if you don't understand it - it's just not on your level, you know? Doesn't mean it's stupid. Pirates 3 was my favorite, I thought the new concepts and deeper plot was pretty amazing, but a little too much for some.
Then again, I think we all need to remember, some movies were made just for pure entertainment. Those can be enjoyable, too, if presented properly.
