I do find Lucia much more likeable than I ever found Julia, who just never seemed to stop whining. Like, bitch, you got into Stanford and you're going to make your friend's suicide all about yourself and use that as an excuse to marry your loser boyfriend? The fuck? Lucia seems to have an actual point instead of just being a generic whiny teenager. I do, however, agree with the posters that Lucia having such a pronounced accent compared to her siblings is distracting, especially that we know she never lived in Mexico and has been raised in Los Angeles her entire life. Her acting coach might want to work with her on that.
However, I kind of miss Claudia. I don't think the Valentina actress quite has the chops that Lacey Chabert did at that age. I mean, she's fine, but Lacey really was one of the most phenomenal child actors captured on t.v. (I don't think she really carried those chops into adulthood, but damned if we don't have the proof of who good she was.)
