I would argue that Beauty and the Beast is the absolute pinnacle of modern Disney animated films. One might even say it is practically perfect in every way. I'm sure some others here would disagree.
That aside, I think the thing that makes BATB feel different in terms of park tie-ins is that something like Frozen felt very rushed and forced. Like Disney was surprised that it was a hit and suddenly said, "Crap, what can we do to capitalize on this? Stick a Frozen logo on that, stat!" I didn't get that vibe from the BATB stuff.
