I had that reaction to 'My Dinner With Andre'. If you ever get a chance see Linklater's 'Waking Life'. 'Before Sunset' with academics...and animated. I loved it but many find it sheer torture. :-)
Linklater's next is an animated PKDick adaptation, I'll be seeing that.
Put me down in the "sheer torture" segment. I could not finish the film. I know others who loved it but, FWIW, to me it seemed like something I used to hear getting stoned in the 70s in college talking about the "ironic angstful meaning of life."
