This film appealed to me as a bilingual, and overall I found it to be lighthearted and a fairly fun watch with friends.
The good news is that the film is shot fairly well, especially with respect to real-deal scenes of East Los Angeles. I greatly enjoyed the music score, which ranged from classic mariachi songs to upbeat Salsa.
I was happy with the cast, and Adriana Barraza (the maid from Babel) steals every scene as aunt Aurelia Jimenez. Wilmer Valderrama is convincing (though cliche-chasing) as the cholo with a heart, and it's great to see him in something different than the "Fez" type characters.
The downside is that the film is a little light on laughs. There are a few laugh-out-loud moments, though they aren't frequent in this movie. There are definitely a few jokes and moments in the film that would be more funny to Spanish speakers, or at least anyone familiar with Mexican-American culture.
Camilla Belle is a solid actress, though I wasn't too sure about her being cast as the lead. Granted Belle's half-Brazilian in real life, but it was bizarre that the producers spray tanned her a nuclear orange color in order to "look the part" of a Mexicana.
Like plenty of rom-coms, From Prada to Nada is certainly predictable, although there were a few minor twists and turns along the way.
As a guy, I thought this was a lighthearted watch, and worth a rental. The ladies I watched it with (also Spanish-speakers) all loved it, and there were more than a couple "Awwwwww!" moments, plus some tears. Not the best romantic comedy I've seen in a long time, but definitely worth renting.
