It's quickly becoming one of my favorite Zelda games. I've heard people talk about how BOTW is Nintendo making Zelda open-world, but I'm pretty sure the original NES Zelda already did that 30 years ago.
I actually really like the characters. To the point that this reincarnation of Zelda herself may be my favorite. As Yahtzee said in his review, she's an insecure nerd that constantly doubts herself and feels she in way over her head. (...Not that I know anyone that. Nope, not me.)
I do have some complaints. First off, the inability to climb at all when it rains. It makes sense, but when the rain is random and I'm trying to get somewhere, I end up just setting the game down for a few minutes and just do something else until it passes. I wish they made it so that the climbing gear set granted you a set bonus that allows you to climb in the rain, at least.
I know a lot of people have complained about the voice acting. Maybe I just have a high tolerance for that kind of thing, but I thought it was...ok. Not great, but serviceable. For the first Zelda game with voices, I expected worse.
Finally, everyone talks about the weapon durability and how awful it is. At first I thought it was bad, yes, but as I played the game and got better weapons, it didn't really become a problem for me. That said, it's almost become the opposite problem for me: I keep finding new weapons, and I constantly get told that my inventory is full. I'm sure this would be less of an issue if I found more Korok seeds to upgrade my weapon slot capability.
All the other nitpicks I have, like sidequest exhaustion and finding all the collectibles, can pretty much be attributed to the fact that it is an open-world game. Heck, I still love the original NES Zelda games, and I got stuck on those all the time when I was a kid.
Overall, it's a solid 9/10 for me.
