It was Pacific Rim, but regardless of director (loved Pan's Labyrinth), this movie is clearly catering to the Michael Bay mindless action crowd which, while having fans of all ages, generally are targeted at teenagers. Maybe that's disputable? Personally I don't think so... Also, it's not so much that people loved the trailer, more that it was 3000 comments of people explaining how much they "just came", and not a single critical voice. I really doubt that would be the case on HN if it had been submitted/allowed here.
