But if you admire movies like Paul Thomas Anderson's The Master, Charlie Kaufman's Synecdoche, New York, Darren Aronofsky's The Fountain, and Terrence Malick's The Tree of Life, you'll almost certainly find value in this one, as well.
Sharing thematic similarities to 2011's critically uneven " The Tree of Life ," the film is less labored but more antiseptic, not as concerned with hazy religious iconography as it is with underlying biology and science.
Comparisons to Terrence Malick and "The Tree of Life," among other Malicks, have abounded ever since director-writer-co-star Shane Carruth's elliptical venture premiered at the Sundance Film Festival.
You'll see shades of The Tree of Life's birth of the universe sequence in his breathtaking mico-photography of chemical reactions, and the cycle of natural world is clearly integral to Upstream.
Where the first half of Primer is full of rapid-fire dialogue with scientific jargon and heady astrophysics theories being ping-ponged back-and-forth like an episode of Gilmore Girls, Upstream Color is a 90-minute meditation on storytelling and the fragile nature of identity and human connection that feels like a feature-length version of the most abstract segments of Terence Malick’s The Tree of Life.
Upstream is overwhelming at times — it’s the only time outside of The Tree of Life’s creation sequence I’ve felt the urge to flee the theater out of sheer overload — but its numinous beauty endures.
