For those of you not so familiar with Mexican telenovelas, there's a general trend in most novelas that a character who is seen praying or otherwise shows signs of being a devout Catholic is practically guaranteed to be one of the good guys, which is understandable seeing how Mexico is a largely Catholic country. "La Rosa de Guadalupe" takes this a step further with the Virgin Mary as the main heroine in every episode... literally.
A typical episode of LRdG goes like this:
1) A person or family is introduced as having a problem of some kind, usually relevant to the intended moral of the episode. Examples include a kidnapped child, a pregnant teenaged girl contemplating abortion, a mother seeking revenge for the brutal murder of her child, and so on and so forth.
2) Eventually, someone prays to the Virgin Mary for help in resolving the problem.
3) A white rose appears, indicating that the Virgin Mary has heard the prayer and is going to help the person/family in distress.
4) Eventually the problem is magically resolved, often with little to no real effort on the part of any other character except for the Virgin Mary. Some episodes even go as far as to show blatantly supernatural displays of the Virgin Mary's power, such as a girl about to be raped suddenly glowing with a heavenly light that burns her would-be rapist's skin.
5) The moral of the episode is summarized by a female voice (presumably the Virgin Mary) as the white rose from #3 disappears.
Overall, the basic concept and intent of the show is actually pretty good, the intent being to teach others (mainly teenagers) important life lessons and/or religious morals.
When it comes to the execution of said concept, however, LRdG falls flat in more ways than one. Several of the topics/themes that the show covers, such as abortion or the kidnapping of a child, are painfully oversimplified and unrealistic, most notably in that the Virgin Mary is portrayed in the show as a fairy godmother who magically resolves all of the protagonists problems with little to no effort or consequences on part of the protagonists themselves. Furthermore, portrayals of certain subcultures such as emos/goths or Otaku cosplayers derive in many ways from highly exaggerated stereotypes of said subcultures to the point that it's insulting. Couple this with bad acting that ranges from completely stiff/wooden performances to fits of melodrama so extreme that you'd think the characters had bipolar disorder, and the end result is a pretentious, unrealistic mess that tries so hard to play on the viewers' emotions that virtually everything else about the plot and about the show as a whole is severely neglected.
Having been raised Catholic myself, I have a healthy respect for religious beliefs of all kinds. If you want to make a Catholic television series to meant to teach people morals (religious or not), good for you, have at it. But in this case, as it stands, "La Rosa de Guadalupe" has failed to deliver its messages in a focused, balanced way, with the primary underlying message being that, instead of trying to solve your problems on your own, all you have to do is pray to the Virgin Mary and let her resolve all of your problems for you.
