On Turner Classic Movies the other night, the theme was Biker Movies. Not my favorite, to be sure, but I can sit through "Easy Rider" and be entertained and, to a lesser degree "The Wild Ones". But I had never seen "The Born Losers" before, and I'm here to tell you that I don't think I've ever seen a worse movie - and I saw "Billy Jack" when it came out in theaters. I love movies, even bad movies, but "The Born Losers" is unwatchable - I had to keep switching it off, but I'd come back just out of sheer curiosity to see how bad it could really get. Some bad movies are bad in a good kind of way (think "Plan 9 From Outer Space") but this combination of a horrible script, cringeworthy acting and (no?) directing is just excruciating. I suspect that "Wild Angels", which came on later, might be another contender for Worst Movie of All Time, but by then I was bad-movied out. What's the worst movie you've ever seen? Gayle, you're already down for "Eraserhead"!
