I thought the same things. Consider the parish I just left: Raging codependant rector who has affairs and is getting divorced, Homosexual assistant rector who hooked up with someone on the internet who filed a harassment complaint when the associate tried to break it off and got the guy fired, parishioner who embezzled half a million from the diocese... Not so far off at all.
FYI..the show's creator/writer had a blog on the ECUSA website..which favored the show..go figure..
I think the show did a real service by showing how corrupt and hopeless the currrent Episcopal Church really is. The writers probably didn't intend it that way, but that's what happened.
