Green Lantern says "retired" too so who knows.
I just don't think it's a big deal but I didn't like or care about most of these rides anyway so I'm fine with it. Green lantern has always been awful, parachutes line took forever even with only a few people on the line. Twister is whatever. The skyride when it was actually open would take longer to get on half the time then just walking across the park.
It's not like the park is just removing stuff and never replacing anything. Ka will be back in some variation in 2026, new flash ride will be open next year. The park could have just gotten rid of all it and never replaced anything and still got decent crowds so at least they are still putting some money back into the park.
