As far as Tsai Ming-Liang, I thought Vive L'Amour was excellent, and I've been told The Hole was as well.  I haven't gotten around to seeing What Time Is It There? either.  I often see Hsiao-Hsien and Ming-Liang compared.. but I'd have to give both of their films another look to decipher why Hsiao-Hsien just doesn't work for me.
