Miserable Cardiff?

Off today to Cardiff (really, really looking forward to the drive down!!)to see the new production of Les Mis at the WMC. Rather conflicted feelings. I worked on the third year of the original production when it was particularly strongly cast (Peter Karrie, Phil Quast, Barry James and Linzi Hateley amongst the principals)and the original production is an absolute classic in terms of direction and design. Can a new production offer a valid alternative or is it just going to be a pallid re-imagining?
