Well I guess I'm the outlier here.
I saw the LA show earlier this week, and I thought it was good. I agree it wasn't as good as the Broadway production but I didn't go in expecting it to be (since when has a tour ever been better than its Broadway counterpart??)... The set was surprisingly well done and the actors were all on point. I particularly enjoyed Matilda (Gabby Gutierrez) and Mr. and Mrs. Wormwood.
Bryce was definitely not as good as Bertie but he also was not bad at all. I thought he played his part very well, and I would not say there was a lack of energy. In the video someone posted above, he does look very awful but I guess he got it together before I saw him because he was nothing like that...
My biggest complaint would be the dialogue and lyrics because (just like the Broadway production) it was very hard to understand some of the kids (although not Matilda).
School Song was definitely cut when I saw it.
Maybe its because I had low expectations for the tour or maybe its because I've always loved Matilda, but I thought the show was pretty good.
