Heavy handed, obscure and repetitive dialogue, coupled with bulky staging, comprise “Kingdom Come,” an over-melodramatic piece about the invasion of the Incan kingdom of Atau Wallpa by the “Red-bearded” infidels, who I always assumed were the Spanish conquistadores, but appear here to be another tribe.

The opening provides some interest; a swinging crate center stage that evokes a picture of the hold on a rocking ship. The crate crashes to the floor and breaks apart.

Several characters enter to pick up the pieces. These characters are described as “survivors from across history,” each from an era where there was war and conquering.

This is supposed to give the piece a universal message, but tends to make it a jumble. The rest of the play just plods along at an unpleasant pace.
