Pacific Rim was the best kaiju flick to come around in a long time, setting the bar for verisimilitude, acting, and perhaps attention to detail thanks to its director. Where the number one complaint against it seems to be its lack of realism, one has to wonder what people were expecting going into a movie about giant robots punching giant monsters. Guess what people, I hate to break it to you, but the entire concept is entirely unrealistic from start to finish. That doesn't mean that, like any good fantasy, it shouldn't make the attempt to look as real as possible (with good matte effects being my primary concern), but just that complaining about the a-realism of an a-realistic movie is not even wrong. One might as well complain about non-representational art not looking like anything in particular.
And that's the thing, that despite a kaiju film not being realistic, it has the fantastic verisimilitude that Guillermo Del Toro brings to all of his fantasy movies, showing a level of design in world-building that lends a certain gravitas to a world in which gravity is not a real issue. And Mr. Del Toro needs to be encouraged to continue to make these rich, visually deep films where attention to detail renders them awesome rather than silly.
Which is why you should watch Pacific Rim move than once, because a single viewing is not really enough to appreciate the entirety of the film. After the initial viewing, knowing what to expect from where the director is directing your attention, you can enjoy all of the little touches in the background that makes Del Toro's films not merely shiny, but lustrous. In other words, if you enjoyed the movie the first time around, you will enjoy multiple viewings of the same film.
And in doing so you will add to the box office that the movie is making. This is important because we want to encourage Del Toro to make more movies like this, and perhaps let studios risk letting him indulge in projects like filming In the Mountains of Madness or whatever else he damn well pleases. At this point I'll turn up to a movie on name recognition of this director alone.
Enjoying this movie again will enable Del Toro to make more movies that you can enjoy. And, perhaps it will mean that other directors and other studios take a long, hard look at Del Toro's formula and start making movies like that, rather than movies like the Lone Ranger or Grown Ups 2.
