What TV couples never got together, much as you wanted them to? Mine:
Captain Picard & Dr. Crusher, Star Trek: The Next Generation.
They had great chemistry, yet the show rarely ever did anything with them. Sure, they got married in "All Good Things..." but that was just an alternate timeline.
Cordelia & Doyle, Angel.
It nearly happened. Sadly, Doyle died a few minutes after Cordelia finally agreed to go out with him. "I guess now we'll never know if this is a face you could learn to love."
Buffy & Xander, Buffy the Vampire Slayer.
Of all the men in her life, I think Xander is the only one (outside of Giles) who really understood her & cared about her. He loved her as a person and as a superhero. Angel & Spike only really loved her as the Slayer. Riley couldn't get past her being stronger than him. Xander is the only one who could handle Buffy being the dominant partner yet still have enough in common with her that they could settle down for a life together when she finally retired.
Buffy & Faith, Buffy the Vampire Slayer.
Isn't it obvious?
All this unintentional sexual tension, yet none of the good stuff.
Malcolm Reed & Hoshi Sato, Star Trek: Enterprise.
It just feels like a good idea to me.
B'Elanna Torres & Seven of Nine, Star Trek: Voyager.
From what I've heard, they considered pairing up Seven with a B'Elanna hologram instead of a Chakotay one in "Human Error." Beyond the obvious
factor, B'Elanna had a passionate spark that Chakotay clearly lacked. It might not have been a healthy relationship but it could have been a lot of fun.
Angel & Kate Lockley, Angel.
I think Angel worked best when he was paired up with more mature women, like Kate or Darla. Unfortunately, Kate simply couldn't deal with Angel being a vampire.
Max & Maria, Roswell.
Max needed to be paired up with a vibrant, zesty woman who could teach him to love life. Max/Liz just enhanced each other's dullness.
Dana Scully & Monica Reyes, The X-Files.
I swear, Reyes is ogling Scully all throughout "Existence."
