It's a great show - and his stage shows (of which I've seen the last three) far outstrip his tv in my view. His last but one show won the Olivier award for Best Entertainment from The Society of London Theatres - which is a prominence for magic in the theatre that hasn't been seen since the days of the Egyptian Hall, I suspect.
If I dared to have a complaint it's that he tends to out-Berglas Berglas with the final reveal in his closer. One or two layman I have spoken to about the show have also, unprompted, highlighted this as a concern (without mentioning Mr Berglas of course!).
Anyway - if you get a chance - see the show and judge yourself - you won't regret it!
