One of the four great Road Movies of the late 60s early 70s, the others being Easy Rider, Two Lane Blacktop and Vanishing Point. Ther'e's an innocence and naiivety in John Wintergreen that's fresher and less nihilistic than the other films. He has ambition, at least at first, a dream of bettering himself. The Driver in Two Lane Blacktop seems locked within his own inertia, unable to exploit the wide horizons he drove towards. Captain America in Easy Rider is lost within a society that doesn't understand him, looking for a utopia that he'll never find. Kowalski, too, in Vanishing Point, has reached a moment when he realises that he's simply too tired to carry on playing the game.
All four films are tragedies, but Electra Glide in Blue retains a sense of innocence throughout in John Wintergreen's irrepressible optimism - even when his dream of becoming a detective goes sour he still retains a sense of good-natured tolerance right up to the end.
