As amazing as the cosplay is, when I looked closely at the picture it looked more like the toys/collectibles they sell than someone in a costume. That can mean one of two things. Either the cosplay is so good it has effectively captured the details, or, not so great, it is so terrible that it looks plastic and stuck. Personally I don't know what to think, it could be any number of things, lighting, angle, material used, the camera itself, coloration, effects, any number of things. Though it does appear my thoughts on the image changes about every time I take a look at it, so it could just be my screen that is making it look funky. I'll take another look later once people start getting up and I can get my glasses and a better screen to look at it.
Sushi, while I can see somewhat where your friend would come up with that, I was more closely reminded of Back Hawk Down, a purely Military movie based on true events, or possibly Wind-Talkers, another military movie based on true events (World War Two, invading the island of saipan and a couple of other small islands on the way to Japan).
Speaking of Halo 4, I am very unsure about the ending. The game itself was spectacular, great graphics, controls were pretty intuitive, the makings of a solid game, but the ending....I don't know. I don't know whether to like it, dislike it, denounce it as out of character (for fan-boyish reasons more than anything), hail it as a masterpiece or just hide in a hole and throw rocks at sticks to make a pizza. :/
