My entire namesake is after this version of the ride, I loved it THAT MUCH. Still miss it to this day. What they did to it is a travesty IMO, especially after how underwhelming the rest of the Avengers Campus land turned out.

I love the Guardians attraction, but it's a shame they had to get rid of ToT. One plus though is it makes it different than any other drop ride in a Disney park. And just like my ladies I like variety hahahahaha.
