Sometimes when one has a craving to satisfy, it isn’t filet mignon that one hankers for, but maybe just a really good burger. Sometimes when one goes to the theatre to see a new show, you don’t know what to expect. Will it be a burger or filet mignon? How will it satisfy an inveterate theatregoer who has seen and reviewed hundreds, if not thousands of performances? A title can give a clue. A press release can titillate the proverbial palate with well chosen tropes. Law and Order: The Musical, a new show with book and lyrics by Ilyse Mimoun and music by Jeremy Adelman, which just opened at The Broadwater Second Stage, tickles expectation. What the show delivers is an umami burger, a delicious pastiche of spoofery, an extended, eighty-minute slice of SNL-esque buffoonery, with a bountiful serving of silly, snappy dialogue garnished with enthusiastic song and dance.
