[in progress 7/1/2013]
There is some real content here: and it is the following. First, that Pacific Rim is an example of a video game character / voice makes the transition from games to film. In this case, its the voice of the computer in Portal and it is also the voice of the computer in the giant robot, I think. It is usually the other way around (e.g. from movie to game). Second, that water in visual effects is hard, very hard. And big water, e.g. water that is scaled up is even harder. I don't care how fast your computers are, although that helps, it is a very tough problem for reasons we can go into later. Third, the plot device of the "neural bridge" has amusing psychosexual implications, I hope they make good use of it. Fourth, its been a long time since we destroyed Tokyo in cinema, I hope the filmmakers are up to the task.
Minor Spoiler Alert, but nothing you would not learn from any trailer.
Whereas previous narrative was limited to "person vs nature", "nature vs nature" and so forth, we can now add "robot vs robot" and "robot vs alien" greatly expanding the range of narrative possibilities.
Thus the fate of this important genre may ride on the box office performance of Pacific Rim. Hollywood being what it is, were Pacific Rim not a "monster" at the box office, and failed, it would impose a chill on the financing of other giant robot projects, no matter how worthy. That is the normal craven behavior of Hollywood and is just a fact of our lives.
Pacific Rim has another first to the best of my knowledge. A voice character from video games has made the transition to feature films. You may recognize the voice of "Portal" in key places in Pacific Rim as the voice of (what I think is) the computer that helps manage the Jaegers. If you listen carefully near the beginning of this trailer, you will hear a very recognizable voice say "Pilot to Pilot connection: engaged".
