We are about halfway through Season 6 using
@flickchick85's list with a few additions here and there, including the 1998 movie. Because I am a glutton for punishment, we are still keeping all of the mytharc episodes through seasons 6 and 7. I plan on probably stopping at Requiem.
Guess I'd better finish my list then!
Seasons 8 & 9 (this is where the MotW quality really took a nosedive as there was far less Gilligan or Darin Morgan involvement at this point -
none in Morgan's case - so there's not a lot here, but still some quality eps):
8x04 "Roadrunners" - another demented town episode, wooo!
8x06 "Redrum" - think
Memento if Guy Pearce were actually living his days in reverse. Quite good, though.
9x04 "4-D" - a serial killer who can traverse parallel universes. Fun concept.
9x07 "John Doe" - a unique Doggett-focused ep. He wakes up in Mexico with no memory of who he is.
9x11 "Audrey Pauley" - A similarly Reyes-centric ep.
9x13 "Improbable" - Burt Reynolds!
9x17 "Release" - This one dives into the murder of Doggett's son, but I'd still count it as a standalone, and a good one at that.
9x18 "Sunshine Days" -
The Brady Bunch, Ben from
Lost, and Vince Gilligan writing/directing. What more could you want, honestly. This is also the last episode Gilligan ever wrote for the show, so kinda bittersweet.
Revival seasons:
10x02 "Founders Mutation" - This really felt like an old-school episode of
the X-Files, which was just nice.
10x03 "Mulder & Scully Meet the Were-Monster" - Thank god they got Darin Morgan back, is all I have to say.
10x04 "Home Again" - Was initially disappointed in this episode given the title and the fact it was a Glen Morgan episode made me think it was a sequel to "Home," but this was still solid and Gillian Anderson was great here.
11x03 "Plus One" - S11 was my preferred revival season because it was mostly MotW's. This is another one that felt like classic
X-Files, elevated by a great guest-performance.
11x04 "The Lost Art of Forehead Sweat" - Darin Morgan tackles the Mandela Effect! Enough said!
11x05 "Ghouli" - This is one of those dual MotW/Mythology eps, but it works.
11x07 "Rm9sbG93ZXJz" - Mulder & Scully vs. Technology! There's barely any dialogue in this episode and it's a joy.
11x08 "Familiar" - One of the darkest eps of these revival seasons. Good stuff.
And that's it! What I consider to be some of the most notably Good-to-Great episodes of one of the truly greatest TV shows of all-time. Hope you make it to the finish line, DK!!
