My first encounter with the talented Jesse L. Martin was in the 2005 movie of the stage play "Rent." He is a very talented singer and has also proven to be an accomplished actor. I enjoyed him more recently in the weekly series "The Flash."
Here he is a producer of the new "The Irrational" weekly series and stars as Alec Mercer. My wife and I watch it streaming on Peacock a day or two after the episode airs, that fits our schedule better.
The concept of a weekly 30-minute or 60-minute TV series is as old as TV. Very few of them over the years have been outstanding but they are competent, they serve a purpose, as mostly light entertainment where we can enjoy the actors and an interesting story line.
Alec is a professor, his theories involve the fact that given certain circumstances people often do irrational things. He uses this when called upon to help solve a crime. In the second episode, which we watched last night, a well-know author comes to him asking help to solve a murder, her own. Seems she was poisoned with Polonium 210 and is dying. (In the story, I found out tobacco can contain small concentrations of Polonium 201, a deadly radioactive substance.)
Anyway, I see there are a few very negative reviews of this show, in my opinion each of them is off base. This is a pleasant show and pretty well stands up to the hundreds or thousands of weekly TV shows over the decades. No one needs to watch it but there is also no reason to bash it.
