I am one of the lucky bastards whose family owns a couple of movie theaters, so I got to see Prometheus this morning in a private screening (me and two other people). We cranked the sound really loud, and since we have Barco DP1200 projectors and XPanD 3D with Dolby Screen Server DSS200, the picture is as good as it gets in these parts of the planet. The viewing room was a 136 seater, meaning a rather small room with excellent acoustics. I saw the first half of the movie sitting rather back of the house, but towards the end I moved to a row 4 for the full impact of the 3D picture. My recommendation is to see Prometheus relatively close to the screen in a smaller theater. I saw the first 23-minutes of the film about a month ago in an industry function in an 800-seater, and it didn't look as good as it did today.
Anyways, the movie is as good as I thought it would be. Visually it is glorious. It is a truly a stunning piece of work when it comes to 3D and CGI. It is not, however, two-hour a digital 3D demo like the third Transformers was. There is actually a story. When sipping my morning espresso at the lounge looking at the poster before seeing the film, I wondered why the poster said "From the director of Gladiator and Black Hawk Down", and not "Kingdom of Heaven and Blade Runner". When you see the film, the aforementioned comes pretty obvious. Those whore are looking for any kind of deep philosophical conversations about the meaning and origin of life are going to be sorely disappointed. Certain causalities (why according to this story humans were genetically engineered, serving what purpose etc.) portrayed in the film are only hinted at, and/or only visually explained during the entire story. To give clues to one of the "big questions": take a close look at the very beginning of the film, a certain picture on the wall in the room with the huge head, and the very end of the film. Those who watched the movie with me earlier today completely missed this.
Those who are more familiar with the art of H.R. Giger are going to find a couple of other older not-Alien-related designs and works of art by the great dark maestro in the movie as well as an added bonus.
Summa summarum: it is dark, it kicks ass, it looks awesome, it makes you think, and it has a lot of not-obvious-by-first-glance stuff in it. I say, go see.
(Edit: the Finnish premiere of Prometheus is actually today, the first public screening at 1800 hours. If I am not entirely mistaken "Prometheus" opens June 8th in the US...)
