Here's my sort of final "stuff actually worth going back to watch" list:
Demon's Souls
DKC: Tropical Freeze Race
Catherine Babel Mode <-- watch the first few minutes to see the concept of the run
BioShock <-- even though the runner cheats near the end.
Dishonored <-- this might be the technically most impressive run in the show so far.
Symphony of the Night Blindfolded
Guacamelee Gold <-- especially the final boss twist
Momodora One-Handed
Silent Hill 3
Resident Evil 2
Donkey Kong 64
DKC3 Race
Hook
Quackshot
Deus Ex <-- best commentary so far.
Max Payne 2 <-- to watch a run completely fail due to PC issues and have to reboot ten minutes later
Streemerz
Gimmick!
Tetris TGM <-- Skip TGM1 and the first race of TGM2. Skip again starting with the blindfolded play.
Two Worlds
The Witness <-- very relaxing
Pause Ahead <-- I'd never heard of this game but it's awesome totally recommended
Super Mario World Low% Small Mario <-- 15 year old doing the streaming
Super Mario Maker <-- maybe watch 5 minutes of this
Pepsiman
Pokemon Blue Reverse Badge Acquisition
TASBot Plays Super Mario Bros 1, 2, 3
TASBot Beats Super Mario Bros 3 in 2 seconds <-- skip the stuff that comes afterwards
I wouldn't go as far as calling things flat out shitty just because they are different or even worse this time around though.
Generally the show hasn't been shitty--there have been a lot of novel games or categories or new tech for old games, and a fair few entertaining commentaries. TAS Block was definitely shitty though. Actively disinteresting for most of the run, tons of setups, pass. If I could get rid of anything, though, it'd be blocks built around games that have super hardcore fanbases but no one cares at all outside the core fanbase (like the Sonic block or Mega Man ZX block). Maybe the solution is that I should just catch up on VODs afterwards and not worry so much about runs I have no interest in, but a huge part of this being exciting is the live, ongoing feeling since I can just watch anything be speedrun any time if I wanted to.
Just out of personal bias, I always hope that at least one of the Metroid Prime games is there every year and I can't see them ever dropping Super Metroid. Pulls in too many donations and, well, I wouldn't want them to.
I would like to see more 90's era DOS stuff, and put my $20 this year toward adding Ultimate Doom. Sure, some flavor of Doom is in pretty much every marathon, but those games run fast and there's generally some cool new trick or commentator. Seeing Strife was neat - it's a game that always interested me back in the day but somehow never played.
Strife was neat. I didn't really like the run but it was neat exposure to something I had missed at release. What an unusual set of modifications to the Doom engine.
