Jim should learn to let go, it's clear that he is milking this subject because he lost ideas for videos, I guess the next one will finally be about another topic, most likely Mass Effect.
Horizon is well executed, however it's not in the same league as Zelda, there's a reason why Breath of the Wild has 58 "perfect" 100 scores at metacritic as of now, something no game achieved before, the 70 from Jim doesn't mean more or less than every single 100 the game got, just opinions. However Zelda shows it has what it takes to appeal to the masses, so it seems to do something right.
That said, I'm glad Sony had the courage to try something completely new and put that much PR effort into the IP to make it a stable in the industry, especially when you know the developer behind it is famous for their Killzone games, I tried hard to like but never really enjoyed as they felt bland and never took risks with the standard FPS formula.
