Oh boy, here we go with me!
Shows:
Digimon (Though I would recommend skipping Frontier and Tri. I have yet to see Xero Wars 2.)
Pokemon (Seriously, SKIP the Black and White Seasons. You will save yourself SO much pain.)
My Little Pony: Friendship is Magic (I need to finish the last two seasons though.)
Yu-gi-oh! (I REFUSE to give Zexal a chance.)
Carmen Sandiego
The Dragon Prince
Castlevania
Ninja Warrior
Mythbusters (Need to get back into that show.)
Ducktales
Power Rangers (Skip Super Megaforce. You'll thank me later.)
Batman (Need to check out Brave & the Bold sometime.)
Kirby (It's actually a good anime.)
Games:
Mass Effect (Even Andromeda, which most of the fandom hates.)
Banjo-Kazooie (I sorta like Nuts & Bolts, but not that much.)
Pokemon (Don't really play Go, Mystery Dungeon, Conquest or Puzzle League.)
Sonic (Everyone and their mother tells you to stay away from the 2006 Release. Take their advice.)
Kirby
Paper Mario (Stay away from Sticker Star.)
Mario & Luigi RPGs
Professor Layton (It ended at Azran Legacy as far as I'm concerned. The last game is not cannon in my eyes.)
Ace Attorney
If I think of anything, I'll edit this post. For now, that's it.
