My favorite is reading the comments here versus some of the posts on the Islands of Adventure threads:
You can't have a HTTYD land, it needs to be a Dreamworks mashup vs You can't have Jurassic Park and Jurassic World in the same area, it's too confusing and disruptive it needs to all be themed to one franchise (even though they are technically the same franchise).
The hub and spoke layout is dumb, you need to be able to go from land to land without exiting first vs Harry Potter is ruined if you enter from The Lost Continent as it's underwhelming and you aren't introduced to the land via the Castle from the bridge, they really should have had only had the single entrance/exit.
The hub and spoke layout is dumb, you have to walk too far to go from one land to the neighboring land vs walking into Islands for Harry Potter doesn't work because you have to walk through Seuss Land and then Lost Continent before you get to the land, they need a bridge across the lagoon directly to Harry Potter and waiting in line for Hagrids queued back to Lost Continent wrecks the experience.
The worlds need to be connected vs Velocicoaster wrecks Harry Potter as you can see/hear the coaster and it breaks the immersion and you're in a tropical jungle in Jurassic World and you see snow capped roofs on the ride.
The park can't have all IP rides and shows, it needs to have something original vs Poseidon's Fury is a waste and needs to be rethemed as Zelda or some other IP.
I'm not saying that everybody should be in agreement in every aspect, and not saying any specific point of view is right or wrong, but it's funny how current conversations going on are completely opposite each other. Guess that's why they say, "You can't please everybody."
