Well I've never been more emotionally impacted by a show than Next to Normal, but I thought If/Then was middling at best. Let's hope that they return to some raw and emotional roots for this project, and 9/11 is certainly a heavy topic for a musical.
I loved this movie, but it is certainly a challenging adaptation. An older guy who gets into a drum circle with the guy illegally crashing in his Manhattan apartment does really scream musical, but I do love this team, so will be there in the audience without question...
