My favorite TV show of all time is
Babylon 5, where there is terrific chemistry between a lot of the characters.
John and Delenn - the primary romantic couple
Londo and G'Kar - ambassadors from two warring races - whose very adversarial relationship took a number of surprising twists and turns over the course of the series.
And a
L&C link: Tracy Scoggins showed up on the 5th Season of the show as the space station commander, 4 years after leaving
L&C...
But the best chemistry for me has been with Lois and Clark (not surprisingly), and with Lee and Amanda on
Scarecrow and Mrs. King. It was a joy watching their relationship develop, just as with L&C.
And another
L&C link: Beverly Garland played Amanda's mother...
