So,  what do they do?  They literally "buy" that production - the set, the director, the choreographer, Mr. Jakoby, Mr. Linden, and Ms. Stevens.  Of course, given the folks who run the theater, Ms. Struthers' role was played by - Cathy Rigby.  It's just a typical, by-the-numbers, "now" adaptation of a movie, without seeming to know what actually made the movie work, a lot of which was - Mr. Matthau and Mr. Lemmon.  Here we get twenty-one boring musical numbers, terrible writing, jokes which mostly don't land, and a show with little plot and no one you really care about, because they're trying to do so many subplots and the grumpy old men take a back seat to those too much of the time.
