Shawn Elliot has been criticizing games like this for a while, and seems to pick on Metal Gear specifically. For more reasons than one, but we don't need to get in to that.
I'd say the language does fit the medium insofar that it provides an interactive storybook experience that you can't find in the medium it's "cheating" off of. It's based off of Kojima's older games, which were basically the same thing- interactive stories. You control the characters' journey while being treated with long breaks of character and plot development. What is wrong with that? People love it. I love it. It works fine. If every game was presented like Half-Life, for example, Half-Life wouldn't be so special. We can have games that borrow from film. Not every game has to be specifically adapted to push a unique "gaming" narrative, especially not Metal Gear. Not at this point. Was he expecting KojiPro to just ignore the series entire legacy and create something completely different? This series had to be wrapped up in a fashion familiar to fans, and hell, I'd say it was even toned down this time. I'm a fan of Shawn, but to be honest, when he talks about this kind of thing, all I hear is, "People shouldn't like this as much as they do because I have a better perspective." or something.
