Great Old TV Episodes...from Perception

The episode NEMESIS, which I'm discussing today, is from a more recent TV series, Perception. It stars Eric McCormack (of Will and Grace fame) as neuroscientist Daniel Pierce, teaching at a university.  His special angle is that he suffers from paranoid schizophrenia, including hallucinations...some of them welcome, like his imaginary girlfriend with whom he works out his problems...and some of them appearing spontaneously, often to assist in his solving of the particular episode's mystery.  To me it's an obvious ripoff of Ron Howard's use of hallucinations in the movie A Beautiful Mind, although that movie's schizophrenic protagonist, the late mathematician John Nash, in real life suffered from delusions, not hallucinations.  Until this episode, it bothered me that both Dr. Pierce and Nash gave the false impression that those with this mental illness were implicitly geniuses, while in truth the intelligence range among them reflects that of the general population.  In this episode I was gratified to see some focus on a character more of the norm in intellectual ability who, while schizophrenic, was not perceiving hallucinations but rather was, like the real Nash, severely deluded.  A newly installed judge has been found stabbed to death and this young schizophrenic man, who has been writing detailed letters to her with his rants about her being an avenging heroine from another world, instantly becomes the chief suspect...but Dr. Pierce and his sidekick FBI agent Kate Moretti (played by Rachel Leigh Cook) think the murderer is someone else. And so the show progresses until the culprit is uncovered.  Pierce also has hired an assistant, Max Lewicki (played by Arjay Smith), whose chief role is to tell him when he's hallucinating something or somebody.  Although the back story and romantic and academic intrigues abound in this series, each episode usually breaks down to Pierce playing the Sherlock Holmes role with Moretti aiding him as the Doctor Watson character. McCormack brings a lot of passion to his portrayal of Pierce, and the episodes tend to hone in on hot, controversial topics as well.  Perception lasted three seasons on TNT from 2012 to 2015 when it was cancelled...when it first came out I watched the first few episodes from the first season but was too taken aback at the derivations from A Beautiful Mind and abandoned it.  Now it's on Amazon Prime and I'm going through it one episode at a time.  One of my favorite features of Perception is that usually with each episode's opening and closing we see Professor Pierce lecturing on an intriguing topic in front of his class: those lecture snippets in themselves are worthy of discussion...
