Man, yeah, this is going to be hard off the top of my head ... going to have to use Jeff's as a starting point, and then look to see what is coming up
Currently Watching :
Too Old to Die Young - An Amazon Prime 10 episode crime/gangster noir series directed by the guy that directed Drive and a few more movies. It is INCREDIBLY SLOW (the camera can pan left to right for what seems like minutes at a time or people sit, not moving and say nothing for 2 or 3 minutes ... very often) but I can't stop watching ... or waiting. I am only finished with episode #2, each episode is about 85 minutes or so

but there is only about 30 minutes of stuff happening in each episode .. I KID YOU NOT. So why is it here on this list? It is co-written by our beloved Ed Brubaker. I have to watch it. I just wish they had a different director. It is waaaaay tooooo slow, trying too hard to be atmospheric.
Need to watch or Finish :
Doom Patrol - Only watched the first three episodes ... pretty good stuff for sure
Legion - Season 3 ... I have what they have aired on my DVR, just need to watch them!
Jessica Jones - Season 3 ... Just haven't been in the mood
Daredevil - Season 3 ... same reason
Punisher - Season 2 ... yep, as above
Preacher - Season 2 & 3, I think? I thought I saw S2, but I have two seasons on my DVR so I guess I didn't? S4 starts 8/4
Up to Date on and/or waiting for :
The Boys S1 - Hitting Amazon Prime the 26th
Pennyworth S1 - Good ole Alfred has a series hitting Epix on the 28th!!!
Watchmen S1 - HBO has been showing clips of this forever! Looks a lot different than the comic, but in a good way
The Witcher S1 - Netflix ... Soon?
His Dark Materials - BBC/HBO 2019 -
THIS looks good!
Castle Rock S2 - Hulu - Where is this show, damn-it?
Titans S2 - The show is really meh ... sorry to hear about the stuntman dying of course
Star Trek: Discovery S3 - The first season was rough, but man did they make up for it with S2. So good!!!
Stranger Things S4 - S3 was better than S2 ... catch up Jeff
The Orville S3 - Slowly becoming what Macfarlane wanted, Star Trek. Dropping some of the funny as well. Good
Lost in Space S2
Star Trek Picard S1
Westworld S3 "Coming down the line in the future with no release date so probably next year or even three years from now if they get made at all" shows
Sandman S1 - Netflix - next year sometime
Y (the Last Man) - FX - not a fan of network tv, so luckily a cable station I like, FX. Really excited for this one!
Lord of the Rings - Amazon - 2021? "Amazon is committed to do a five season series"
Wheel of Time - Amazon ... again? That is what they are saying. But with Sony on this one so probably outsourced.
Game of Thrones- HBO ... three prequels/sequels are in the works
Dark Tower - Amazon ... jeez, Amazon is pushing the right stuff. Hope all this happens!
Ghost Rider - Hulu ... Yeah, I like the character.
Helstrom - Hulu ... You tell me as a kid that Son of Satan would have a show, I'd have laughed in your face.
Cursed - Netflix - 2020 ... King Arthur. Yeppers, I like that stuff
Conan - Amazon (again) ... This one currently being pushed less due to the other Amazon fantasy stuff

2025?
Also excited about the new shows Disney will have (The Mandalorian, Wanda and Vision, Falcon and Winter Soldier. Loki, Hawkeye and What if ... !!!!!) as well as the Hulu animated stuff featuring Howard the Duck, Hit Monkey, Tigra, Modoc and Dazzler.
Some good stuff coming folks!!
And even though I am not interested, I just can't believe the are doing this, but for those that love the show, they are also creating yet another Walking Dead series. Yep, three Walking Dead tv shows will soon be on the air
Also, if you are a fan of Terry Pratchett and/or Neil Gaiman, their collaboration GOOD OMENS is on Amazon as well right now. Its about a demon and an angel working together to stop Armageddon. It was ... okay. Not bad, at all, but wanted a tad ... I don't know. It was fine

EDIT - Crap, I forgot about Man in High Castle!!! I nee to rewatch S1 and then hit S2 !!!
EDIT 2 - to drop in some trailers!
