I have been posting and lurking on this board for 2 years, so I have read a lot of posts. There are posters on here who seem to have very similar views to me, and I trust their opinions. After reading their views on the show I would have been tempted to stay away, SO I can't fault people for saying that they probably would leave the show at intermission, even thought they haven't seen it.
I did get a free ticket during previews, and I made it through to curtain call. However, I was quite tempted to leave. The only reason I stayed was to see how much of a train wreck it would turn out to be.
The funny thing is that Little women (at least the first act) was better than Cry baby, but so boring that I left.
I guess it really comes down to Schadenfreude vs. Ennui when it comes to leaving.
Other than that, did you enjoy the play Mrs Lincoln?
