The show itself was great and thoroughly enjoyed by our daughter. The length of the show was just right, as was the level of interaction.
Whilst the show was great the items on sale before and after the show were very poor quality. The spinnig handheld toy we purchased on the way in had broken before we left the theatre (the staff did replace it for us though). The toy Ben Horn broken down and wouldn't make a sound by the evening. And the antenna of the soft ladybird toy character had come off the same night (which is a serious safety issue as it could be a choking part.
All in all, I would highly recommend the show..but avoid the over-priced cheap and dangerous items they sell at the show.
I've given the show an overall rating of 4 out of 5. It would have been a 5 had it not been for the faulty sale items which caused my daughter to cry later in the evening.
