I was there too. This was my 10th time seeing it and I thought it was the worst show I saw. Alice came back way too soon IMO. She was straining and struggling to even sing during most of it. Rushing through lines especially in Next to Normal. Jenn could barely finish her line when Alice started hers.
I wasn't crazy about Brian. He looked way too old even next to Alice. His voice was too scratchy and deep for my liking. Maybe I'm just used to Bobby since I saw him 9 other times.
Kyle Dean and Jenn were at their best. Kyle just gets better and better and so does Jenn. She struggled once in Superboy(which she usually does). Jenn was just so animated onstage and looked like she was having a blast. I never once saw her break character like the OP said. She has laughed in Hey#3 everytime I saw the show.
Louis and Adam were the same as they usually are.
That being said I thought Alice and Brian had incredible chemistry. He did with Jenn and Kyle Dean too. I Am The One(Reprise) made me cry harder then I usually do.
These are just my opinions but I know people are gonna bash me like usual. People like different things/people but no one seems to realize that.
Don't believe everything that you hear! Only the peeps involved know the truth!
