I'm with the room, this film has been sadly overlooked as it was at the time of it's release (even Mazursky champion Pauline Kael was Luke warm) and deserves to be seen.
I think this sort of autobiographical film had sort of been overdone, so Mazurky's film was lumped in as "one of those." What was missed, I think, was his unsentimental, adult perspective on the time and place, on what it meant to be young and bright. He gives us something of what the beak nick world might have been like, unlike the silly portrayals done AT THE TIME.
Lenny Baker, in his only major lead, is excellent along with the entire cast. Christopher Walken makes an impression without the hamming that would later endear him to so many.
