At first glance, the water temple looks the same!
Every door, lined up with each other on every floor! It's kind of tricky to know where to go sometimes. If I played OoT today, I'd find it a little difficult.
But again, like McBlizzy said, it's very unique. Come on, give it a rest about the boots. What do you expect right? Link is a human. (not like an actual Zora in MM which was amazing)
The direction is hard to follow, which people hate about it but at the same time, that's what people like about it. People like a challenging temple.
As an impatient little child (like i was) I didn't like it. But now, I find it enjoyable.
