I speak no spanish at all and I did not find it distracting. In fact, I loved ABLT in Spanish. The power of the emotions was so huge that you get the point and yes, I think it makes it more authentic. Just think of it as Opera.
Then again, I didn't think Cody was bad at all either so what do I know? I thought he played the "cool" and collected leader perfectly. I also thought Karen Olivo danced a storm, so again, I seem to be in the minority/positive outlook here.
(On the other hand, as much as I love this new WSS, Hair (at least in the Park) was a stronger show and if I had to pick between the two, Hair wins by a small margin).
As for the rush discussion, Rent started out GENERAL rush. not just student rush. Anybody could have done it. Most rushes started out that way, only in the last few years have they all seemed to make it only for students.
