About as close to bad as a Zelda game gets, which is to say it's really not all awful. There are some very fun dungeons, clever puzzles and a few decent bosses, but it's severely hindered by finicky controls that are often unreliable and of course the repetitive Temple of the Ocean King. Pretty much every cool thing comes with some kind of caveat related to these two issues, and in the end it's nowhere near as satisfying as just about any other game in the series.
