If it’s been literally years, you know the new writers and director are probably going to screw everything up relative to the original, and there will also probably be a change in cast.
I’d much prefer to forget the original than have a good memory of it and be disappointed with the changes.
This happened to my wife and I with season 4 or Ozark. Fortunately I found a well made video on YouTube that summarized Seasons 1-3. I was amazed at how much stuff we had forgotten.
Lately I've just been rewatching the final episode of the previous season before starting a new one. I'm a little lost in that episode but by the end I'm following along, and it's usually an exciting finale episode that gets me excited to watch the next episode.
Well, if you have enough time to watch season 2 than you have enough time to watch season 1.
At least you know that you loved season one, if you truly forgot everything about it than you get to enjoy it again. Season 2 could suck, you never know.
I love it when I forget TV shows and movies. I can't rewatch them if I know what's going to happen.
