IDK. I still like the WDW parks (and I fully admit to their faults and flaws, there are many) and I visited Disneyland for the first time ten years ago and I came away wowed, but I think it's a bit overly revered just because it's Walt's park. It's charming, though, very much so. I LOVE that park. I'd move in if I could. But for me it's not exactly like caviar on fine china (Disneyland) to bugs in the dirt served on a paper plate (WDW).
I think one of the main problems with WDW (and believe me, there are more than this, like lack of significant expansion until now and even now they're not doing all they should), is that we need some unique things. I know they don't care about that, and while I selfishly want certain attractions to be cloned here, what makes WDW stand out? For me it would be Animal Kingdom but then many aren't impressed by it like I am (yes it needs a few more attractions). Epcot's World Showcase is a draw. Future World is a hot mess and seems like it will continue to be.
Disneyland has the draw of it being Walt's park. And I'm not trying to discount that or dismiss it. It's major.
WDW used to be a destination that was talked about. People KNEW Epcot. It was ingrained in pop culture.
I'm not really making my point so I'll stop rambling on but I think the parks need to be unique and stand out. Clones don't really help that.
