Isn't that true of any system though? If you missed your 60 day window for FastPass+, you weren't getting Flight of Passage. If you overslept until 9:05am with normal FastPass, you weren't getting Toy Story Mania. If you didn't arrive at the park until 10:30 and everything was standby-only, you'd be waiting 90 minutes for Space Mountain.
I get that people don't like that it costs extra. Fine, yes, it's a price increase, nobody is disputing that. But in terms of coming out ahead or behind from using it, Genie+ is good for people who are good at Genie+, just like FastPass+ was good for people who were good at FastPass+ and FastPass was good for people who were good at FastPass.
