MacGyver was a 1980s TV show in which a young Richard Dean Anderson was very competent and solved problems. I think he was sort of a consulting secret agent, the way Holmes was a consulting detective? He worked for a place called the Phoenix Foundation and was sent around the world to, like, help people who were being menaced. But don't worry even on his days off he still ended up in situation where he had to be very competent and solve problems.

I actually did watch a considerable amount of this show in reruns in the late aughties! I never did get more than a very vague idea of the setup or, indeed, anything except a very young RDA being ludicrously competent at everything and making the world better. It was one of those shows from back when every episode had to stand alone and they didn't have to make everything part of a giant mytharc where you have to have just binged the previous six seasons to know what's going on - instead, nobody expected you to ever know what was going on, and that was fine, just watch RDA be competent and pretty. (Am I the only one who misses those days?) You had to catch certain very specific episodes if you wanted any kind of backstory or character arc, and I think I missed most of them. The theme music was very good, it was my ringtone for awhile, and RDA was very competent and determined and ethical and pretty.

(There was also a reboot? That ran six seasons and only just ended? I know zilch about it. It does not seem to have made much of a splash.)

There isn't a ton of fanfic for it and I have read even less, but a lot of what exists is MacGyver/Murdoc. Don't ask me to remember anything about Murdoc either - he's some kind of recurring antagonist? An assassin? Works for the bad guys?

Anyway there is one M/M fic that's on my "never lose track of" list. I don't know that it's "good" by today's standards but sometimes you just want a really good oldfashioned h/c amnesiafic enemyslash extreme whump wallow, right? And this one is the best at being what it is. So only one link today. It's on insanejournal!

• Oh My Enemy by janecarnall
  21 chapters, MacGyver/Murdoc, explicit, needs Archive warnings for probably violence and torture and dubcon? Suicidal ideation. etc.
  
  Murdoc is released from the hospital, still partially disabled by his injuries, with no memory at all and his only link to his past and his identity the person who paid his hospitals bills: one Angus MacGyver, who must care a lot about him to do that for him. But when Murdoc shows up on MacGyver's doorstop, almost out of money and barely able to walk, MacGyver isn't acting like somebody who cares about him...
  
  (Note: if you follow the links on the chapters, they sometimes go back to a deleted LJ; keep clicking back to the memories linked in the rec and you can read it all.)

...hey, the first fandom on this list where I didn't have a tag!
