Just came back from Avengers Campus! Here are my thoughts:
I don't know if it was the fact that our boarding group situation couldn't have gone any better, or I came in with rock bottom expectations, or it's a recency bias, but I had a really awesome time inside Avengers Campus. My party and I spent our first four hours inside the land, and it really couldn't have been any smoother: we got our BG at 7, got to the parking structure at 7:40, into the park by 8:20, and in Web Slingers' queue by 8:30.
Web Slingers is a cute, inoffensive ride that works given the limited real estate it occupies. It's fine, not amazing, and certainly not worth the stress over getting a BG. I did enjoy it because I'm a CS guy who's amazed at the motion tracking tech behind it; the UX design of the on-ride system is pretty nice too (on the screen in front of you prior to shooting webs, you can see the splines that map to your hands as a way to check if you're being tracked properly). The latency is minimal; it's super responsive.
Things I didn't mind but you might: It
is an arm workout (whether that's good or bad depends on you). It definitely skews on the younger side with the cheerful AI, STEM bent. The physical mapping of Avengers Campus in this ride is utter doodoo—somehow you can U-turn into an alley and you're behind the Test Kitchen, and then another U-turn and you're by the exit.
We were super early in the land, so Pym Test Kitchen was still serving breakfast. We waited in standby because of the new rolling system they had for mobile order (to avoid a repeat of opening day, they open return windows in like 3 hour blocks). I got the Calculated Breakfast, and my sibling got the Impossible version. Both were good! I liked the focaccia, tater tots, and Impossible sausage.
Also got to try a few of the cocktails at the Pym Tasting Lab. The Particle Fizz (hard seltzer, cherry popping boba) was meh; somehow tasted even less fruit than a La Croix, and it was supposed to be POG-flavored! The Honey Buzz was delicious; like a sweet Moscow mule. Definitely will get one again.
The land would be absolutely nothing without the character interactions though, for sure. In the span of the few hours we were in the land, we saw the Spiderman stuntronic, a training session led by Okoye, and a Black Widow/Black Panther vs. Taskmaster stunt show; all of them (with the exception of Okoye) also held meet and greets. There was no schedule; it all happened relatively spontaneously (though you could predict that something would happen when there was an influx of cast members doing crowd flow).
The land is punching up much higher than the ride, restaurant, and shop will have you believe. You can almost delude yourself into the CAMPUS backstory as a call-to-action for superheroes because everyone's here and ready to party in the land. Take away the shows, and you're left with what Galaxy's Edge is now except with worse infrastructure.
TL;DR the ride is fine, the food is good, the character experiences make the land.
(Unrelated, but we rode Guardians twice with no wait because it was restricted to the land, so another plus in our experience!)
EDIT: Also just remembered! We tried the Pingo Doce and didn't like it. It's essentially Vanilla Mountain Dew and it's a strange taste.
