The women are attractive but the talent pool for serious acting (at least in western eyes) is rather shallow. THere have been a few good movies out, the one that sticks out is Water, but most of them are over-the-top escapist nonesense that has very little appeal to the general American audience. So trying to transport the actors/actresses that do well in that form of environment into hollywood might be difficult.
but then again the talent threshold for stardom in the united states isn't necessarily that high. just need a pretty face and body. just look at jessica alba. absolutely no talent but hot as hell.
