I watched about a half hour of it on Prime last night and agree that it's never looked better than here, but I was impatient and switched over to the videotaped production of Pippin.
I watched the DVD this afternoon. My overall impression as a teenager was still viable for me: ponderous, only sporadically funny. Great music, wonderful cinematography, and everyone's trying so hard to make it work, but it mostly falls flat.
And the DVD was in visually rough shape to put it...
The DVD has been sitting on my shelf for a long time unopened. I, too, saw it as a teen in its original release in the 1960s and was underwhelmed though I liked the cast very much. I might need to open it some time this week and watch it again to see if I would have any interest in the Blu-ray...
