In the 1950s Paddy Chayefsky wrote a successful drama, Middle of the Night, in which nobody could understand what a young Gena Rowlands could see in an old Edward G. Robinson. Or, in the movie version, what Kim Novak could see in Fredric March. That quandary is back, after a fashion, with Mr. Parker, Michael McKeever’s sort-of-new drama (it premiered in Florida in 2018). Only this time it’s hard to see what Davi Santos sees in Derek Smith.
