Hmm, how to sum up Ang Lee. Well, he's very inconsisent, at a technical level; I get the sense that he doesn't bring much to the table there and is at the mercy of his collaborators. Narratively, he's shaky, too, with his films often displaying a weak storytelling sense. His strength, though, is a strong feel for his characters and environment, together with occasional bursts of visual creativity; that's what makes his films generally worth checking out, but also, perhaps, very inconsistent.
If I recall correctly, the shot of the fireworks in Brokeback, though great in isolation, doesn't quite gel with the surrounding shots; true or not, that's a good metaphor for Lee's work as a whole, I think.
I'm voting "Unpredictable, but I'm always interested," even though that's a little strong. I've had zero interest in catching up with Ride with the Devil, for instance.
