saw the show last Thursday in Liverpool - and still not sure how I think it compares to the others.
It was the liveliest crowd I've ever been a part of (maybe because it was Liverpool?), so that was fun.
I did enjoy the show, and found it both funny and entertaining, but was slightly disappointed afterwards. Derren does tend to stick with his formula, so I think I was disappointed because he never really suprised me. It was the "please write xxx on a piece of paper", then a light and funny first half, a darker second half, then the suprising finale. Most effects were the same (and in the same order) as in Enigma, just with a change of storyline.
But overall: it's a really good show, and on the same level as the others. I'm just spoilt after seeing him live several times
One part had the potential to be much scarier and creepier, and at that point I really wished Andy Nyman had been a part of Svengali as well.
I agree with the Stoner that if you know your Mentalism 101 the show is an amazing lesson in how to make amazing stories out of basic effects.
Personally I think I enjoyed Enigma the most because of the medallion, and the finale, which were both amazing in their own way.
