I'd recommend Sankey Unleashed, 20 Years of Sankey, and his "The Very Best of" DVD set if you decide that maybe he's not as bad as you thought. All three of these products are full of great effects.
EXACTLY what I was about to type, you hit the nail on the head. Sankey does release a little too much material at times, but some of his material is very good. I am very selective in buying Sankey material, so all that I do get is usually quality for the most part. Also 'Beyond Secrets,' 'RCM,' and 'Front Row Sankey' is quality material.
I agree with you.
Sankey is a very creative guy. Creating magic is what he does. Like any artist, he needs an outlet for his creativity. I believe when Sankey was younger, he released more of his material through columns in magic magazines.
Now I guess he's turned to DVDs. Can't really blame him. Why give it away for free in a magazine when he can charge for it?
His vast output is only a problem if you're a fanboy and try to buy every single thing he releases. No one else needs to do that. I doubt that Sankey would expect everyone to buy everything he markets.
