Beyond the Gorn and Sleestaks, I'm not familiar with a lot of live-action lizard men. I just for the impression that they were staying away from the miniature Godzilla Lizard and sticking closer to his first appearance.
I can understand not liking the look but that doesn't really have anything to do with how it's rendered.
I'm more comparing it to the dinosaurs in Jurassic Park which came out, what, close to twenty years ago. The special effects for ASM took me out of the movie everytime the Lizard was on screen.
Doc Ock in the second Raimi movie, in comparison, looked great.
