I really don't know what to make of Bug, William Friedkin's bizarre tale of either delusional paranoia OR a sinister government plot to control the masses through the use of genetically engineered parasitic insects: it's certainly one of the strangest and most perplexing films I've seen in recent years, Friedkin messing with his viewers' heads so that they become as unsure about what is reality as the central characters. It was certainly a far cry from what I would call 'enjoyable', particularly when viewed as a study of mental illness ('harrowing' would be a better description), and the film's pacing is tortuously slow at times. 'Interesting' is a better descriptor...
Solid performances aside, where Bug scores most points in my eyes is in never resolving its many questions, leaving the viewer to pore over what has happened, dissect the evidence, and come to their own conclusion about what they have just witnessed. Although it seems probable that Peter and Agnes were seriously messed in the head and imagining the whole infestation, one cannot say this with absolute certainty; besides, sometimes its more fun to simply believe the less likely explanation.
