If you believe everything you just stated, then you haven't played much of the game. I've put over 4000+ hours into my first save and am still playing and finding new things. Every shrine is completely different and new from the rest, and lots of them have enemies. There's always something new to see on every inch of the map (which, by the way, is one of the largest in all of gaming), and nothing feels too "samey." Side quests will keep you entertained for months if you're a casual player, and no two of them are alike. The Korok seed challenge is intended for the completionists, and if any of what I just mentioned isn't for you, then don't complain about it. This is all opinion, and the fact that you disliked the game doesn't make it "flawed," not does it make it rushed. In fact, the game was delayed twice in 3 years, so they could make the most of what it could be. It was worked on for 6 years total, and I think they achieved that goal. Once again, this is entirely opinion. You are not correct, nor am I, nor is anyone.
