Here’s an excerpt from the review by Judd Hollander:
An interesting aspect of the play is its construction. Dionysus appears at the outset and then disappears for over 30 minutes. Indeed, many of the characters appear only once in the play, with the majority of the story told by the Chorus (consisting of 12 women) through verse, dance, and movement. (According to the script notes, the play was originally envisioned this way and is probably one reason why it is not done often now.)
Casting is quite good. Groff, with his boyish looks and devil-may-care attitude, makes a perfect Dionysus. He appears fun-loving and regal, yet at the same time, is violent and cruel when crossed. The text also nicely mixes humor with an undercurrent of danger in the verbal duels between Dionysus and Pentheus. Here the disguised god bedevils the king with answers that seemingly have no meaning and an uncaring attitude that drives Pentheus to distraction.
