It was okay, a mixed bag-moments of brilliant exposition, moments that fell flat. The promise of the premise exceeded the end result.
The "blanket" thing was amusing concept, and film referenced sensory deprivation experiments (which I've read about & find interesting but not in terms of trying it myself).
The duality it kept returning to made sense-we humans tend to wish for things to be reducable to a satisfactory concluding or originating singularity or simple rule/absolute reality. Instead, life is comprised of the yin-yang/push-pull/approach-avoid/relativity & subjectivity of "it's both simultaneously", or "it depends on how you look at it".
