It sounds like this all boils down to a few things...
The book of LB is poorly constructed, leaving the leading role and those supporting her to flounder to make up for bad writing.
Orfeh did nothing for me either. She was loud, but not funny. She wasn't bad, so don't jump down my throat. She was perfectly serviceable, but nothing special in my eyes. I never really looked forward to her return to the stage after she'd been off a while. She is plagued with an abosolutey atrocious number (Irish-something-or-other), an inappropriate accent, and bad costumes. I'd really like to see her in a show that focuses on her talents, and that is written accordingly.
Kate Shindle was the only supporting player who even kept my attention throughout the whirlwind, non-stop blast in the face that was LB, but I don't think she deserves a Tony nom either.
Maybe it's just me, but Richard H. Blake and Andy Karl look like twins! I had (and still have) trouble distinguishing them from each other. I wish the casting director would have gone with a different "type" for one of those roles. They're both kind of bland and generic and neither one seems like they stand out from the crowd.
Itty Bitty Geisha?
Toyland?
