I have it on bluray, borrowed it from my brother, and it's been lying on the windowsill for months.
I have a strong gut feeling that I will hate it. I know what I can expect from Malick, and it's 2:18 hours long, so I have a feeling that it could be extremely pretentious, but I can't know for sure. I thought "The New World" was really bad, but The Thin Red Line was really good (!), apart from those "poetic" parts with voice over, very pretentious. But the cinematography was nice, and Elias Koteas was good, among others.
But Brad Pitt is one of my most hated actors along with Colin Farrell (and Steven Seagal I guess, though I never watch Steven Seagal-movies), so Pitt could enhance the badness. I mean, he sucks! And I hate Sean Penn too.
By the way, I hated "Into The Wild", and I'm guessing it could be a little like that film, or how about "Legends of the fall", or "Benjamin Buttons Life" (Or whatever it was called.
Yeah, my feeling is that I will hate it, but I'm still curious..
