The "Asian Dragonland" theme is not very good, honestly. If taken purely for fantasy, which I guess it should be, it's alright I guess, but personally I'm not very interested in it. It doesn't even seem very "Asian" to me except for some cultural building styles and euipment choices. Some of the figures look bad with crazy colour combinations and such, and there really isn't much to make the theme "Asian" instead of any other sort of fantasy. And the dragons who wield weapons? They look hilariously bad! 

 And they certainly aren't based off of southeast Asian dragons.
I really do think that the theme is highly based off of Lego's Ninjago, which is a bit disappointing... An historical theme would have been great, and I know that cheng was especially hoping for such a theme. 
Basically, I think that the ninja and warrior in Series 5 of the Fi?ures line are better than those released in the main theme! 

 The only things that I see in the new theme that I really want are the scimitars or dao-like swords and the composite bow.
