I was there last night too and he was my least favorite since Neil; of course it's a tough task following JCM, but it's hard to forgive the pitch problems and wonky accent work. His timing with comedy will surely get better (can't get worse), but he fell into the trap of pushing too hard with Hedwig. The subtlety that JCM and Michael C. Hall brought to the role is completely missing from Criss' portrayal.
As others said, his strongest moments where in the last 15 minutes.
The audience was rather obnoxious; at one quiet moment someone screamed out, "we are not worthy," and I thought, "shut up! It's not like Liza's up there!"
The funniest line of the night was when Criss ad-libbed(?), "If you had wanted to see a mess on stage you should have gone to Dr. Zhivago." That perked me up, but otherwise my mind wandered a lot and I was happy to be on my way home.
Marie: Don't be in such a hurry about that pretty little chippy in Frisco.
Tony: Eh, she's a no chip!
