That movie started out well, but it went to crap before the end. I don't know about anyone else, but I was disappointed by DOOM the movie.
As far as Space Marines go, the idea is appealing but probably unrealistic. For the time being, it's just too expensive to get into space. Besides that, most of that article seemed to be singing the praises of the V-22. As it relates to the V-22, I'm always a sceptic of new technology until someone demonstrates its superiority. I don't know if I'm seeing a significant advantage to it.
