Targets is a great example of the good old days when indie films had plots instead of character studies, were aimed at mass audiences instead of the festival crowd and the awards circuit and when hungry young directors could elevate exploitation flicks into something much more challenging.
Tim Kelly, surprisingly like a more wholesome white-bread Matt Damon, is the all-American boy who one day buys a rifle and plenty of ammo, kills his family and moves on to shooting random human targets, first from a water tower and subsequently from behind the screen at a drive-in movie theatre where Boris Karloff's disillusioned horror star is due to make his last personal appearance. No explanations, no motives, just impersonal mechanical violence that's far worse than any horror film. Similarly, it could be argued that there's no real `point' to the film - just a sad observation of the way that reality can be far worse than the imagination. In many ways Peter Bogdanovich still hasn't made a better film.
Although not extras heavy, the lengthy introduction featurette with Bogdanovich and the director's audio commentary more than make up in quality what the disc lacks in quantity.
