I'm concerned about it, partly because I don't really get a warm fuzzy about a director when you tell me he directed The Day After Tomorrow. That movie was really bad. I probably would have just kept quiet about being involved in that movie if it were me.
This looks from the preview like it's going to rely much too heavily on special effects to be any good. We are, however, probably just seeing all the footage from a single 5-minute segment of the film, and the real question is what they do with all the time not shown in the previews.
Despite my high level of skepticism, I usually enjoy John Cusack's acting, and often find his movies more interesting and thoughtful than I expect. There's at least a glimmer of hope, I suppose.
