Hey hey hey... leave justice league alone. It's a great INDOOR ride with A/C, despite having flaws lol (those Cyborg, Joker & Harley AAs are pretty impressive for a Six Flags park)
I'd argue it was less of a family attempt & more so an indoor ride in general attempt.
In regards to a "family coaster" (hate that term), I'd almost rather they get rid of Magic Flyers, Speedy & Cayon Blaster since they're junk off-the-shelf kiddie coasters, but at least one needs to stay for the younger crowd (Canyon Blaster!!). Then add something like the new Camp Snoopy coaster Knott's is getting. Also, get new trains on Roadrunner Express, the shoe trains are tacky.
Bugs Bunny World in general needs an overhaul. Whistlestop is a waste due to the defunct Thomas The Tank Engine IP
