They never caught my attention either. Clearly very talented, but not my cup of tea. Maybe it could be an acquired taste, but I'll leave that FOMO on the floor.
The Magic Circle absolutely does not like revealing the trick. Penn and Teller are all about revealing the trick. They see it more or less as their moral duty to make sure you know THERE IS NO MAGIC HERE.
I've always respected them a great amount for that. I'm glad that The Magic Circle finally came around.
It's one thing to reveal standards like the cups and ball, but another entirely different to spoil a recent trick a living magician is still making money off. I don't think they do the latter.
The balls and cups with transparent cups is still amazing, by the way.
I never got their act, so I never really watched them, but my relatives thought they were great.
Anyway, I did like and enjoy their performance in Babylon 5.
