[BotW][TotK] Shrines are a bad substitute for dungeons
Something I see a lot when the quantity/quality of dungeons in the Wild era games gets called into question is the idea that dungeons haven't really gone anywhere, they've just been broken down into shrines and sprinkled across the open world. I'm sure this was the Zelda team's intent, and on paper it's not a terrible idea... but I think the execution totally misses the mark.
Go back to Zelda 1 and try to break its dungeons down into individual "puzzles". You wind up with a very small pool of interactions: pushing a block, clearing a room of enemies, bombing a wall. Not great for a "puzzle game", but then the fun of dungeons didn't come from puzzle execution. It came from entering these mysterious cryptic spaces, riddling out where these interactions could happen, and using them as stepping stones in the larger navigation puzzle of exploring/mastering the dungeon. Along the way you'd deal with traps and enemies, find new tools and upgrades, and leave the dungeon feeling like you'd made major progress. Later Zelda dungeons would make the puzzle interactions more complex and cut down on navigation complexity, but I think this basic appeal stayed consistent.
Now, let's think about shrines. You're generally presented with a single type of interaction (which is spelled out to you via text when you enter), always in a Portal-esque austere sound stage. There is no mystery, there is no connection to the larger world or structure of the game, there is no reward or progress apart from a predictable fractional upgrade to your health/stamina. This is only puzzle execution, in a vacuum, at the expense of everything else.
If I throw out my expectations for Zelda games and try to appreciate the shrines as puzzles on their own terms... I still don't think most of them are very good. How could they be? The fact that they can be played in any order means you can't have the kind of difficulty curve or elaboration on mechanics that you see in puzzle games like Portal, Baba Is You, etc. The designers have an impossible task of making 120-150 "Level 1"s. It's not shocking that they pad out this number with Tests of Strengths and Rauru's Blessings.
Worth noting that I think the quests to find shrines can be really great! This is where all the fun stuff about Zelda puzzles lives in the Wild era games IMO: mystery, discovery, danger, connection to the larger world. The only bad part about these is that they all end with, y'know, the player finding another shrine.
