They just don't hold up all that well. Last Man... is better than the other, although that's not saying much.Also, you can see where George Romero borrowed heavily for his Night of the Living Dead flicks.I must add: Richard Matheson is a highly respected genre writer. Besides writing LAST MAN ON EARTH (among other books and screenplays) He's the guy who wrote the excellent DUEL,starring Dennis Weaver. Get it, if you've never seen it.I really don't blame him or the late Vincent Price for the way LAST MAN... turned out. It's really not a bad flick...and yet you can't help feeling that it should have turned out far better, that the material was there...Hey, if you're about ten years old...you might get a real kick out of it.
