The game has a time limit for dungeons and it's three day cycle makes for a certain amount of repetition.
The thing with that is that if you play the game well, you should never be pressed for time. If you've ever run out of time in the middle of a dungeon you probably
A) Didn't use the inverted song of time
B) Didn't reset time after getting the dungeon's song
C) Suck at Zelda games.
If you give yourself a full 3 days with the inverted song of time, there's no way you should ever be pressed for time in any dungeon.
And as for repetition, the only example I can think of (outside of sidequests) where you could conceivably have to repeat anything is defeating Goht a second time to get Epona. And even that's not so bad, considering you can warp directly to the boss room after beating the dungeon once.
Hate? Really? I didn't think anyone could have such a negative reaction to such a delightful game.
I used to dislike (I won't say HATE) Lttp until very recently. I still think the first 3 dungeons are utter crap and are totally boring. But almost immediately after that, the game really picked up and I ended up loving it (I 100%'d it within a week after that point).
I think part of the problem is that early in the game, you're so weak. Most enemies do 1 heart of damage, so 3 hits and you're dead. And it takes half a dozen hits to kill even common enemies at times. As you go, you get the master sword, better armor, and more items, which makes the combat more than hit and run tactics. Also the dungeons become more challenging and interesting puzzle-wise, so it doesn't feel like going through the motions.
TL;DR The beginning of LttP sucks. Insanolord, give it another chance, you might end up liking it.
