It’s easy to enjoy the teenagers who take center stage in the latest production by Actors’ Theatre, “The Burnt Part Boys.” The family dynamics between older and younger teens, separated by just four years, is explored. The 14-year-olds are still in a bit of a make-believe world, while the older boys are taking on the realities of manhood. The conflict that ensues puts each on an adventure up a West Virginia mountainside, one group hot on the trail of the other. It’s within that concurrent journey their stories emerge.
