I've enjoyed it overall, I just wish it was more difficult. Hero mode + no bed healing makes it better, but most of the dungeons are completely linear and don't give you the opportunity to get lost (which has been an issue with Zelda dungeons for quite a while). I'm at either the 2nd or 3rd to last dungeon and have finally had a single "huh" moment where I needed to look at the map. That should have been happening since the beginning IMO.
Unpopular opinion I'm sure, but I actually remember the water temples from OOT and MM fondly, in the sense that they had me sitting puzzled at the map at multiple points. That feeling of being lost in a maze, and the subsequent "AHA" moment is what I've been missing from the Zelda series. TOTK had moments like these, but they rarely paid off and weren't found in the temples.
