What is the author's style in Arsenic and Old Lace by Joseph Kesselring?

Some of the language and references used throughout this play will seem to be somewhat dated to modern audiences, although the language was most likely considered to be current and even “cutting edge” when the play was written. In particular, some of the references used in the play (for example, Mortimer’s references to the Zolotow list, and Walter Winchell’s radio program) will be unfamiliar to many readers, and the particulars of Theodore Roosevelt’s life (as presented by Teddy) will not be as well known to audiences today as they were when the play was first staged in 1941. However, by and large the ‘madcap’ nature of the comedy holds up well, and the play remains entertaining even 70 years after it was first performed.
