A man turned into a robot and your looking for it to make functional sense lol and that IMO would be an air vent to allow for air to cool him off..
This is the one problem I have is most ppl on the Internet are making such stretches to hate this movie... If you hate a movie for the suit you my friend have no idea how story telling works.
And ppl who say it looks like batman/iron man that's the whole point. It's satire making fun of the movies that have that look as major company in OCP would want to market there killer cop to kids and the best way would be to make him look like batman..
When the movie comes are and we hate the way they told the story I understand hating it but hating it because of damn suit or because they aren't playing tv spots 6 months ahead of release that the movie will suck and not make money.. The first teaser for the new die hard came out in October of last year and that movie as horrible as it was still made money. The post comic con stuff will be where we take this film not set photos.. Some ppl just hate to hate. Sorry their remaking our favorite movies but grow up ppl
