Bah, i dont understand why you judge gonzo only by its most extreme and questionable movies/scenes.
Im not even into anal, go figure!
There is out there a LOT of great gonzo porn without the mentioned circus tricks, AND in the same time without boring and pathetic stories that I AM SURE you all features viewers make large use of Fast Forward button over them.
Why should i watch Evan Stone acting if i can avoid it?

Check out gonzo made by Jules Jordan, Joey Silvera or Chris Streams, and you'll see what i mean (and many other porn-makers).
