(PLAWT.hol)

n.

An obvious element missing from the plot of a movie, television show, play, or book.

Is dialogue that sounds like it could be spoken by actual human beings (rather than a marketing VP) too much to ask? Can the audience NOT be insulted by having to step over gaping plotholes every third scene?

The Eddie Capra Mysteries (NBC) bring the true whodunit back to television in a style slightly sprightlier than NBC's campy "Ellery Queen." Again, though, the audience is supplied clues as the sleuth, in this case a feisty maverick lawyer, collects them. Vincent Baggetta as Capra and Wendy Phillips as his very close neighbor Lacey Brown established a sweet rapport in the program's already televised pilot show that should help sustain interest even if the mysteries run into plotholes.

This blend of plot and pothole (1909) has been a staple of the movie and TV reviewer's vocabularly since at least the late 70s.
