Paul Thomas Anderson’s “Inherent Vice” is a 1970s Los Angeles-set neo-noir detective story that deserves a second look. Starring Joaquin Phoenix, it’s a complex, hazy blend of humor and melancholy, exploring love, loss, and the lingering impact of the 1960s. Despite its initially mixed reception, “Inherent Vice” is a poignant meditation on change and the enduring power of the past.
