Okay, the thing is, this isn't a movie you can really rate on a site like this because a few things need to be taken into account:
1) It was a statue. Some of this is meant to be seen in 3D. 2) It's non-narrative. Even for Lynch, there's no real way to approach it, only "experience it". Which in the case of seeing it in real life, would be vastly interesting, but through the medium of the television it's only slightly so. Think about it like seeing a screensaver picture of the Eiffel Tower instead of being there. You can still appreciate it's magnificence, but you still haven't seen it. 3) It was an experiment. An award winning experiment, but still an experiment.
So for that, it's at least interesting. It honestly makes me want to see the actual set up to get a better idea of what all the various forms helped do for each other (animation, projection, sculpture, painting, etc.). But as a filmed medium, it's just something to sit and watch a while, nod your head in acceptance, and move on.
Still, I'd check it out. The idea behind it is inventive enough that maybe it'll open up more ideas for like experiments or further experiments.
