Certain theatrical works are so inherently satisfying that they're pretty great even when their productions are only pretty good, and some are so firmly entrenched as classics that nothing less than spectacular will do. West Side Story is the rare piece that's actually both - a thrilling entertainment that many of us have seen way too many times - and the Timber Lake Playhouse's West Side Story is both, as well; it starts out as pretty good passing for pretty great, and ends up spectacular. By its finale, director James Beaudry's offering had morphed into one of the smartest, most impassioned versions of this legendary Bernstein/Sondheim/Laurents collaboration I've yet seen. It just took a while to get there.
