As it's Telemundo doing it, it may be a flop. But not so much, as in many countries this may be seen LIVE. They have an international channel where they broadcast almost every show they have and every soap they've done.
And in my country, two channels broadcast their awards shows and soaps, so there's a slight chance that one of these channel may do so here in DR (I doubt it though, but who knows).
I hope that the casting is not 80% of Mexicans and 20% all of the other Latinamerican ethnicities that exists in the US. Balance will be a key, and there's tons of diversity to be found in the US, so they better do a great job on that.
