For example, the original (https://thrillingdetective.com/2019/05/30/robert-mccall-the-equalizer/) Equalizer (https://www.get.tv/gettv-blog/10-surprising-facts-about-equalizer) TV series (https://www.dvdtalk.com/reviews/review/66180) with (https://www.original-cin.ca/posts/2018/7/20/the-equalizer-2-lame-sequel-ramps-ups-the-action-dumbs-down-the-premise) Edward Woodward could be looked at as being a contemporary update (https://moviechat.org/tt0050025/Have-Gun-Will-Travel/58c7225e5ec57f0478ebc9d7/HGWT-had-a-reboot-in-the-80s-The-Equalizer) of Have Gun, Will Travel (https://tvtropes.org/pmwiki/pmwiki.php/Series/HaveGunWillTravel).

Possibly the various shows Starring Lucille Ball - I Love Lucy, The Lucy Show, Here's Lucy, and Life with Lucy all had similar themes and situations even the other characters were carry overs from the previous show. Ethal and Viv, Mr. Mooney, Harrison Carter and Cutris McGibbon.

Also The Odd Couple and Laverne are Shirley could be one in the same.
