A theatergoer going into "Little House on the Prairie: The Musical" knows that it will be a decent show - meaning no profanity, no cleavage and no "adult" themes.
But the show currently at the Paper Mill Playhouse in Millburn turns out to be decent in the other sense of the word: Adequate. Nothing special.
Sit-through-able.
This Saturday, there will be a long day's journey into night at the George Street Playhouse.
