Despite my love for the series, I'd say most Zelda games are weak replays. Despite having a lot going on they aren't very mechanically rich, and most of their challenges and ideas are one note, so once you've seen them once, there's very little to gain from seeing them again.
The exception, of course, are the "open air" games, which are obviously very complex and interesting mechanically. But they still don't have good enough challenges or ideas to make use of those mechanics in a way that satisfied me on a replay. It's far too easy to accidentally succeed in a boring way. They're also far too reliant on grinding materials in order to do anything interesting, so it's a hard pill to swallow.
