As far as any generic circus is concerned, "Quidam" by Cirque Du Soleil was pretty good. The music was excellent and the numbers were interesting.

However, as far as Cirque Do Soleil is concerned (and their remarkable, world class shows) this is probably one of their weaker productions. The artistic quality is more or less up there, but the technique of performers is substantially lower than usual.

The good news is that tickets are much less expensive for Quidam than anything else I've seen by Cirque Do Soleil, and there are plenty of unsold seats.
