It's hard to know how to sum up MGS4 in a single word. 'Epic' could be used, but that might imply that small details are out of focus when they're not. 'Gargantuan' is a possibility, but then 'bloated' would also have to be strongly considered. Excellent? Definitely. Awesome? It's awe-inspiring in many respects. Extravagant? Oh yes.
So I'll do my best to sum it up, to give you a brief idea of how good it is, in, oh, about two and a half thousand words. That way I might just about scratch the surface of the content Kojima has jam-packed into this particular Blu-ray.
Despite all the technical wizardry on show, there's still a sense that we're being deprived of valuable gameplay for the sake of some flashy (albeit very, very flashy) story exposition. One or two sections of gameplay, too, are merely adequate and functional rather than exhilarating - but then we're all fans here, and that in itself means our expectations were maybe unreasonably high. It can't all be fireworks?!
So while MGS4's wilfully exclusive, staunch old-school feel (note that despite this, the interface and much of the story is perhaps the most accessible it's ever been - there's just loads of it) may prevent it being the perfect iteration of the series, it also has to be applauded. It hasn't been diluted, it's just as hardcore a Metal Gear experience as ever, if not more so given the abundance of information to process and take in.
