Definitely THE FERRYMAN and TORCH SONG for plays. For musicals...out of all the new ones running right now this season, I'd say only THE PROM is worth your dollars. The more exciting choices are likely to open in the Spring. Stick to the plays, for now!
"The Spectacle has, indeed, an emotional attraction of its own, but, of all the parts, it is the least artistic, and connected least with the art of poetry. For the power of Tragedy, we may be sure, is felt even apart from representation and actors. Besides, the production of spectacular effects depends more on the art of the stage machinist than on that of the poet."
--Aristotle
