Ehh, put me in the Legendary lands camp. At least it rolls off the tongue easier. I mean, having "fantastic" in the park name is a bit too "pat on the back" for me. Especially when a few of the "worlds" are very likely to be less than fantastic.
Why do they have to have "epic", "fantastic", etc? It reminds me of those cheap small-business ads on TV. And it shows a complete and utter lack of creativity.
