I don't think Eovia intends Carrara to be mainly a landscape application. With C4 you get a very powerful modeling package that vue can't come close too(c4 pro comes with amapi 7 as well as 5 other modelers).You also get a very decent animation package too. With the new terrains,sky you can do some pretty nice landscapes with carrara that I think compete very well with Vue. What were you expecting.
