This show is really, really, REALLY good! We got to see it with my children's school yesterday. The Japanese group is performing "The Wizard of Oz". It's not scary. There are some moments when it is dark in the theater, but my little girl was not scared at all, even though she is scared easily. The dialog is all Chinese recording.
There are a few shows in Taipei city this weekend (Oct 2, Oct 3), then in a few places around Taiwan the next couple of weeks. Scroll down to the blue text at the bottom of the page to see where the show is.
