Sounds like a film that could be to my taste. But I always feel bad if people walk out of a film I consider (at least) interesting, although they have paid for it, and especially during a festival. This also happened a couple of times at the Berlin Film Festival this year.
By chance I got the opportunity to rewatch Reygadas` Batailla en el cielo in my hometown Ptuj (yes, it got theatrical distribution here ) and one third of the people walked out of it during the first 30 minutes, while another third seemed bored or laughed at it. Afterwards I talked with a few of those, who told me that they didn`t understand what the film was trying to say. Too bad that many people dismiss difficult films very fast and even more don`t even think about watching movies more than once...

I would like to see the films madhubam mentioned, and am anxious to see the Top list. 

I`ll make mine later cause I`m going to watch Tykwer`s The Perfume today and maybe also Gibson`s Apocalypto. I`m currently staying with some friends and we won`t be doing much more besides watching movies today. 
I think I`ll finish for now, as I have to catch ski jumping on TV. 

Edit: Looks like well only watch Apocalypto and ski-jumping doesn`t start until 3:30.
