I'm actually pretty content with where Avengers Campus will end up. It certainly helps that Mission Breakout is a great experience on its own rather than a downgrade from Terror of Terror. I'm also a fool who likes Web Slingers (good arm workout!) and hopefully a few people will come around on that when it's not the newest ride at the park.
However, the way this land was rolled out was terrible and should never happen again. At least all the dregs of the DCA 3.0 era (Pixar Pier, Avengers Campus) are finally getting fixed to make them more cohesive.
Also, yes, I am defining the new slate of rides as DCA 4.0, with the eras being defined as follows.
DCA 1.0 (2001-2006): The California Postcard Era, spanning from the park's opening to the removal/addition of various rides that "quickly" fixed some of the park's weak points.
Illustrative Rides: Superstar Limo, Soarin', Tower of Terror, Mike and Sulley
DCA 2.0 (2007-2015): Rework Era, spanning from the announcement of the rework to the Grizzly Airfield expansion. An era that aimed to comprehensively address issues with the original resort while making the overall park more thematically cohesive and in line with the quality expected of Disney resorts.
Illustrative Rides: Toy Story Midway Mania, World of Color, Radiator Springs Racers, Grizzly Airfield Retheme of Condor Flats
DCA 3.0 (2015-2025): Chapek Era, exemplified by unnecessary rethemes of existing attractions to better integrate with popular intellectual properties as well as botched reworks or additions that undid a lot of the positive steps made in the previous era.
Illustrative (uh) Things: Mission Breakout, Incredicoaster, Web-Slingers, San Fransokyo Square.
DCA 4.0 (2025-?) Healing Era, where (hopefully) the park improves upon the deficiencies of the 3.0 era without explicitly rejecting them as happened in the 1.0 Era.
Illustrative Rides: Infinity Defense, Coco Boat Ride, ??
