This whole family friendly thing is quite moot at this point:
1) We have no idea what the ride is going to be like
2) It's up to the park to define what they mean by it. I don't think Universal will be building a wacky-worm here...
Arguing that anything less than a 120ft+ multi-inversion coaster won't be thrilling is crazy.
TH13TEEN is deemed a family-coaster but I found it pretty thrilling yet with a lower-height restriction.
Taron looks insanely fun for a family-coaster.
