'Summer Tour' documentary review: Deadheads blissed-out and navel-gazing

The documentary "Summer Tour" follows Deadheads — devoted Grateful Dead fans who have turned touring into a way of life — capturing their search for tribal, spiritual connection. Critics praise its honest portrayal of an alternative lifestyle but note its self-indulgent, navel-gazing quality. The film draws comparisons to both "Wayne's World" and the cult horror "Midsommar" for its atmosphere.
