The overall design and look of the park is phenomenal, and the Adventure Isle and the Pirate area and their respective rides look amazing. But I still think it's light on rides overall...not as much as Hong Kong Disney when it opened, but still. Although what's great about this park is that even though it's relatively light on ride count, they have a ton of shows, and there's a lot of immersive environments and themeing, which can be an attraction itself.
The walk through Star Wars and Marvel "attractions" made me laugh, obviously last minute additions they didn't account for originally. Would've been cool to see big plans ready from the start for Marvel and/or Star Wars over there, but like you said, they need certain things in their back pocket for "expansion".
Two of the biggest things I hate though:
Carthay Circle Theatre on Mickey Avenue. They shouldn't clone that...even though WDW has a tiny clone of their own.
And two: that disgusting sky in Shanghai. Bob Iger's interview with ABC News with the Storybook Castle in the background depressed me.
