Sounds to me like Mr. Lewis has been rather lazy and not bothered to keep up to date with his craft.
Yes you may only need a few moves to accomplish basic effects, but that makes you no better than any sod who has googled "card magic tricks".
Plus I watched your performance of that effect you did on some interview your "son" posted a couple of days ago. I found it cheesy and boring and not at all entertaining.
But before you start what I presume will be a wonderful retort full of hilarious statements, I agree with this:
Sometimes you have to use a sleight since it is the most direct way of acheiving the effect but you can have too much of a good thing and these new monstrosities that young magicians show me should be consigned to the dustbin
A lack of performance knowledge leads to this. Everything should look natural. And many of these things you are talking about do not. But many of them do.
