If they didn't oversell it, or if they positioned this as a Stage One of BRT (such as York Region's VIVA enhanced bus to BRT did,) it might have been a better deal. If you look through the JTA's promotional language on the website, they're really going for the "largest system of its kind in the Southeast" and "bus rapid transit" and all that.
Tampa, for example, backed WAY down in their language when MetroRapid was going to merely be a snazzy bus.
As said, for people already using transit, this is super cool for them. If you're going for a behavioral modal shift, you, at the very least, need exclusive lames and probably island stations. In the US, I'd say you'd also need those over designed buses that look like bullet trains sort of.
