Review of The Hunt for the Zodiac Killer

Ok, it's watchable, quite well made, particularly if you're a serial killer tragic (is that a wierd thing to be into?). Tenuous, very circumstantial 'evidence' has them virtually hang, draw and quarter the first suspect, despite ignoring some other rather obvious and glaring glitches in their suspicions (an English major spelling that badly?). Another laughable point has a 'sniffer dog' find a tree (wow, dog sniffs tree!) and one of the bozo's finds a spot that has been dug over (well, he reckons) - near a camp site. Er, it's not only bears that excrete in the woods bud. Campsite, hole in the ground - hello? Next oooh, man in the early '70's uses "what's your zodiac sign?" as pick up line. Must be a serial killer 'cause nobody else would ever do that then, right? Oh and hey, law enforcement guys, when on camera (or for that matter, talking to a member of the public) wearing your shades doesn't make you look cool & serious. It makes you look insecure and untrustworthy and is not camera friendly. Ooh, found larvae when digging for a body - OF A FIFTY YEAR OLD MURDER. Grubs don't eat bones boys! Oh and some earth has grubs just hanging out! Any time they get close to actual real evidence, they drop the ball and move on (why not give the San Fran theatre man a photo ID parade?) Maybe afraid they'll be proved wrong in their wild guessing? Honestly, if this is US investigation at its best, no wonder they resort to lynching and the death penalty. Git it done before questions can be asked.
