Most of Mexico's telenovelas are nothing but stereotypical characters, no matter what the nationality. The Mexicans, both the good ones and the evil ones, are stereotypes, the blacks are stereotypes (I remember an old telenovela from the mid-70s called La Esclava Isaura, you would have collapsed from looking at it), the indigenous are stereotypes, if there's a Frenchman in the script, mais oui aussi! It's one of the reasons telenovelas are generally so very easy to understand: the characters are predictable precisely because they are stereotypical.
I wouldn't get too worked up because an American is depicted the way so many people believe Americans to be. There's usually more truth to it than lies. Don't forget the line from Robert Burns: "O wad some Power the giftie gie us, To see oursels as ithers see us!"
And I've been recommending watching telenovelas as a way of attuning one's ear to Spanish and gaining vocabulary for lo these many years. Not a new thing, but certainly useful and fun.
