For some (many?) of us, the Ramirez performance makes/breaks SPAMALOT, because it's an honest-to-God bonafide musical comedy performance, with just the right comedic size and vocal prowess. The gents, bless the talented lot, all are playing sustained sketch comedy, albeit wonderfully. Not many musical theater chops are required of the others. (Curry's role is the glue that holds it together--but is it really a delish part?)
La Ramirez stands out because the role was created freshly for this show, from the ground up, not borrowed, lifted or reinvented. I loved her, but hate to imagine the damned thing without her.
People will rant, but I think there's something suspect about a show that is so performance-specific and can't (yet) find a cover to approximate the values of the star's work. The show's flatness without Ramirez reveals SPAMALOT's inherent flimsiness as much as this gifted singing comedienne's impact.
