Since I couldn't write it better myself, I'm posting the conclusion of Plugged In's (Focus on the Family's movie review service) Eclipse review. The body of the review is helpful as well, especially if you're trying to decide if there is anything positive about this movie - and guess what? - there is! Just read the review.
Here is the conclusion of the review by Paul Asay, which makes the most sense I've read in a long time about this series and Eclipse in particular.
Before walking into The Twilight Saga: Eclipse, I expected the audience to consist mostly of girls in the 13 to 18 age range. You know, the demographic that might go to a Justin Bieber concert.
I was wrong.
Granted, there were plenty of young women. But many were in their 30s and 40s. Even 50s. And let me tell you, they were into it: They cheered kisses. They cheered shirtless appearances. They saved their biggest hurrah for Edward's proposal. I don't know whether this was the "Team Edward" vs. "Team Jacob" dynamic at work, or whether these fans were just absorbed in the story, but they couldn't help applauding whenever any of 'em exchanged lip gloss.
In short, these viewers were engrossed in the film's fantasy world—and I'm not talking about the whole vampire-and-werewolf fantasy. I'm talking about the film's fantastical view of love. Eclipse, like all the Twilight films, is far more about romance than horror. And almost all romances, by their very nature, idealize both love and the lovers involved.
In some ways, that's manifested pretty positively here, and some of these values should be idealized. It's great to see Edward being so careful with Bella's virtue and so gentlemanly throughout, for instance. More folks in the real world should aspire to such chivalry.
But Eclipse takes that romanticism to another level, giving us two male protagonists who are practically godlike: Edward is a knight in shining skin who props his beloved Bella on a pedestal; Jacob is a dark-haired pinup idol, sensitive and vulnerable even as he's virile and strong. They are creatures of pure imagination—preternaturally powerful and kind and desirable and desirous. No wonder teens who are still mulling what true love looks like are attracted to these characters. No wonder grown women—many of them who fell in love, got married and found their relationships weren't wall-to-wall passion and joy forever and ever—find themselves drawn to them, too. (emphasis mine -jeh)
In this sense, I suspect The Twilight Saga, particularly Eclipse, feeds our already unrealistic, sky-high expectations about what romantic relationships should look like. I don't think a lot of teens will walk out wishing to be vampires or werewolves. But many of them (and more than a few adults, it would seem) may pine for the sort of love and attention Bella receives from her supernatural suitors.
The film—which is better artistically than the first two—has some other problems as well. I mourn the fact that Bella is so bent on becoming a vampire. Setting aside, for a minute, the ethics of becoming undead, the fact she wants to jump into this irreversible decision feels terribly hasty. Bella's own father comes across as practically powerless to influence his daughter's life, yet another reason for sorrow. (emphasis mine -jeh) Eclipse is also darker and more violent than the first two entries in the franchise. The decapitation scenes in particular were especially jarring. And sex is obviously becoming a bigger and bigger issue for Edward and Bella.
As I left the theater, though, I thought less about those things and more about the American inclination to idealize love. That inclination can sometimes make real love—an undeniably great and wonderful but complex roller coaster—feel a little like a disappointment.
It's telling, perhaps, that Eclipse's supposed love triangle isn't much of a triangle at all. Bella is Edward's girl. She always was, always will be. She chooses a charming, bloodless, idealized man over one of flesh and blood who's arguably more fallible, more real.
And I can't help but wonder, how many Twilight fans are being encouraged to shop for love in the very same way?
