It could go either way. West Side Story's subject matter hasn't really aged much, Romeo and Juliet's essentially timeless, and systemic and personal racism still bedevil the US. I think the music could be a big hurdle. The songs are very much of the style that was common for musicals in the 1950s, which tended not to have the big pounding singalong choruses that tend to define more modern stuff. Also Bernstein was really flexing his composing muscles so it's full of dissonance and complex structures and all of it's tied together by motifs, and it's largely not that toe tapping. "America" is the most conventional thing in it, and it's like that because it's thematically divorced from all the other music in the show. The dancing also ties a lot of it together, it's a lot more like a ballet in form than a lot of other musicals, which has always made it kind of an outlier. I think a good production of West Side Story could do very well, but I don't think it'll pull the same kind of repeat business as other recent more conventional musicals, so they'll need to get more unique bums on seats.
