Actually, this is the first movie ever I walked out on. I left the theater after about 30 minutes. Yes, it was pretty, but that was everything. It was so painfully "artsy" filled with crap about life and all of its clichés. I also felt uneasy about the strong suggestive religious ideas they were forcing on me.
Anyway, I had enough of baby feet, slow shots of kids, and 10 minutes of space nebulas and similar things on our planet. "OOOH I SEE WHAT YOU MADE ME REALISE. WE ARE AAALLL SO SMAAAL IN THIS WORLLD! Oh you writer, you so clever -_-"
Anyway, me and my friend were not the only ones who left, there were like 10 others leaving. So for whatever reason you had, you weren't alone.
