The question is not whether Red Dawn is a good movie. It is a bad movie. As the crazed ghost of Louis Althusser might say, it has always already been a bad movie. The question is: What kind of bad movie is it?
(Aside: The question I have received most frequently when I've told people I went to see Red Dawn was actually: "Does Chris Hemsworth take off his shirt?" The answer, I'm sorry to say, is no. All of the characters remain pretty scrupulously clothed through the film. The movie's rated PG-13, a designation significant to its predecessor, so all it can do is show a lot of carnage, not carnality. May I suggest Google Images?)
My companion and I found Red Dawn to be an entertaining bad movie. I feel no shame in admitting that the film entertained me; I'm against, in principal, the concept of "guilty pleasures" and am not much interested in shaming anybody for what are superficial, even autonomic, joys. (That doesn't mean we can't examine our joys and pleasures.) No generally-well-intentioned, "diversity"-loving, pinko commie bourgeois armchair lefty like me can go into a movie like Red Dawn and expect to see a nuanced study of geopolitics. I knew what I was in for. I got what I expected: a right-wing action-adventure movie based on a yellow peril premise. Red Dawn is an unironic remake of a 1984 movie predicated on paranoid right-wing fantasies; it's not aspiring to even the most basic Starship Troopers-levels of intertextuality and metacommentary. There's none of the winking at the audiences that fills so many other 1980s remakes and homages (e.g. Expendables 2, which relies on the audience's knowledge of its stars' greatest hits — the only convincing performance in the movie is that of Jean-Claude van Damme, who, apparently overjoyed to be released from the purgatory of straight-to-DVD movies, plays it all for real, and becomes the only element of any interest in the whole thing). The closest Red Dawn comes to acknowledging its position in the cinemasphere happens when it turns the first film's very serious male-bonding moment of drinking deer blood into a practical joke, giving the characters a few rare laughs.
What are we supposed to feel good about in this movie? The 1984 Red Dawn was not even remotely a feel-good movie, but it gave us a space in which to feel proud of an idea of America that could survive even the most devastating attack by the Soviet Union (and its Latin American minions). It made a point of showing concrete objective correlatives for the abstract idea that is "American freedom" — the one that was most impressed on me by my father when we first watched Red Dawn together was the scene where Soviet soldiers talk about going to a gun shop to collect the federal Form 4473s, and using them to track down gun owners. This, to my father and many other people, demonstrated exactly why even the most minimal type of registration of guns is not merely annoying, but a threat to freedom. I vividly remember my father saying, "If the Russians come, we burn those damn forms." Red Dawn was not merely an action movie; it was a documentary.
