Sorry to say, this film suffers in comparison with the extraordinary WEATHER UNDERGROUND, which managed to become an unexpected commercial success, largely on the strength of meticulous film-making which not only recounted the history, but also captured context and diverse commentary on the events, times and people central to its' story. It was a film that - in many ways - raised the bar on recent-historical documentary film-making.
Alas, GUERRILLA is a far more pedestrian affair, mostly a compendium of archival footage (much of which is fascinating), with precious little digging into context - the fragmentation of the American left during the early 70s, the rise of underground radicalism (Weathermen, PLO, IRA, Red Brigade, et. al.), the post-60s decline of many major American cities (and the rising despair that ultimately fueled the crack wars of the 80s/90s and the riots that hit Miami and Los Angeles). Each of these elements are of some relevance to what's being presented in this documentary - the SLA were weirder and wiggier than most, mixing their Mao and inner-city blues with a big dose of dadaist strangeness, but they didn't just materialize out of the ether, and - in keeping the focus too tightly on the events and the group, this doc plays the history out as some ultra-violent theatre-of-the-absurd, in real life; a sort-of weird-sploitative pigs-vs-the-people melodrama.
This does a great disservice to history - through this film, Patti Hearst remains an enigma, with a great many class issues, psychological issues (post-traumatic stress, or the Stockholm syndrome) barely touched upon. The other surviving members of the SLA get plenty of screen time (unlike Hearst, who I assume didn't want to be involved), but the many interviews presented don't really seem to dig into anything deeper than who-did-what.
GUERRILLA isn't a total failure by a long shot; anyone with any memory of the 70s knows how weird the story seemed to be, and the recounting of it seen here is definitely captivating; the strangeness, chaos and confusion of the era doesn't feel very distant at all. But I also recall something else: back in the late 80s, the rock band Camper Van Beethoven recorded a snappy, satirical homage to Patty Hearst, entitled "Tania." In three-and-a-half minutes, I think they might have outdone this 90-minute documentary. Oh well.
