Here's my deal on Orton. The guy isn't a great showman; he's not a spot machine, and he's not a great talker (though he does have his moments when he actually sounds passionate, instead of constipated). But he's a good old-school heel. He emotes in the ring, even if it is over the top. His moveset isn't spectacular, but he manages to make what he does look good. Note the way he looms as he circles a guy, and you'll note he doesn't just stomp the body; if he's worked a certain part, he'll go after it. As much as everyone decries his chinlocks, he usually works his rests and spots in a good rythym, resulting in a rollercoaster type of feel -- up-tempo, then down, then up, then down again. It's not as exciting to watch as some, but it's dramatically compelling. The big moves he does have he hits very well: dropkick, weird backbreaker, clothesline, RKO. And while that's not exactly a huge repetoire, it's enough to hang with a Benoit or Michaels who can set the pace.
In general, he seems to get the storytelling aspect of wrestling, and his ringwork isn't bad at all -- just more deliberate. I could never, EVER buy him as a top face for that reason, but as a heel it works for me. I think it's a shame he doesn't have two or three more inches and 30 pounds on his frame, as he'd fit well as a "monster heel" with his size and offense. But I still like him.
