He's talking about it right now:

What I gather so far:
Thinks the map can be kinda empty
Doesn't like the climbing mechanic
Doesn't think the cooking mechanic is very well done for something so important to the game.
Listening to this now. I decided to pick the game up for the Wii U and hope for the best. I'm about 15 hours into Horizon and honestly feel the same way about that as he does about BOTW. I just haven't been able to get into it. I'm still playing it. It's good, but I'm not feeling the ridiculous "game changer" reviews. It kind of reminds me how I felt about Shadows of Mordor when it came out. The reviews were just insane, but it never got its hooks in.
There's also the possibility I'm just open world fatigued. It's Zelda though, so I'm still going to give it a shot (because I know I'll buy it eventually anyways) and see if it grabs me.
