Badlands was Malick's only good film with Sissy Spacek and Martin Sheen as Charlie Starkweather on a murderous rampage.
Just finished watching Oldboy and it was intersting, messed up more than anything. I don't regret watching and wouldn't go as far as to say it "sucks" but it's very easy to see why it's not for everyone. I still have to digest it a bit before I can really say how I feel.
