Me too although it's not quite my least favorite. For me it's definitely the excessive linearity of the game that irks me most. It just bothers me to no end when a game forces you along a single path unnecessarily. The overworld was most of the cause of this for me. What's the point of blocking paths and forcing players along through hallway-like areas besides restricting freedom?When I recently ordered my Zelda games this game ended up last. Even though it is last it doesn't mean I hate the game. I love all Zelda games.
The worst part of this game was really hard to decide since they are very close. When I got to think about it, I thought it was the linearity of the whole game. There didn't seem to be much room for deviation in what you are able to do.
I love this game and have completed it several times.
