I saw this on Saturday. I thought it was a nice piece of writing, though there are some shortcomings in the portrayal of the ambiguity concerning the relationship between the Falco and McKean characters. The acting was excellent, especially Falco and Scolari. Not a riveting show, but I found it satisfying and sometimes poignant.
(As far as seating, I was third row orchestra, and I've never sat in the balcony in that theatre, so I can't help with that)
