You might think that is great, but most people will disagree that grinding the story to a halt and rambling on for an hour is a good thing. It fails on pretty much every level of quality storytelling. It might appeal to you personally but to most people, it's pretentious and counterintuitive to how a good storyteller would work a philosophy into a plot.

Complex Story? YAY!
Too Much Shooting? Boo!

 Unless the reviewer is talking about complexity in the sense that the story doesn't make any logical sense ( as opposed to the story being beyond his powers of comprehension) then he is a complete idiot.

 And how the hell can you complain about too much shooting in a story intensive game ?

MGS is a hardcore series so the story is understandably complex.

Anyways, is story and storytelling the sames thing?

clearly this reviewer has not read MGS for dummies, next time he/she should pick up a copy before reviewing for it will save alot of headache throughout..

Boss fights too complex...

At least even with their different tastes it scored a 92.

 You won't understand MGS4.  Just play the first three for $30 then if you like it spend the 60 on MGS 4.  

Too much shooting?

Uhh... This is a Stealth-action game... Shooting is somewhat necessary, but most people are able to be taken out by CQC.

Then your mind must be seriously fucked up.

First, A story isn't better just because of how many themes you pull out of your ass. In MGS2 various themes were touched (not as many as Deus Ex), but how they were shown to the gamer was nothing more than a clusterfuck, and a shallow presentation. Almost every time the themes were brought up was in such a superficial way like the characters talking directly about them, rather than just let them be noticed indirectly like through simbology across the game.

Planescape: Torment has the best game writing of all time, and the best plot. It reached into the deep infinite hole when showing their themes: Immortality, auto-analysis, alternation and confrontation of self, and punishment. Those were the main ones, but there were a few small ones such as confidence and mistrust, consensus reality, etc...

As for Deus Ex, hell, it touches more themes than the entire MGS series (as I said before). Those themes hide in the seemingly generic plot, and spur out mostly on an indirect fashion, and it when it was directly it was well written, concise and bending perfectly in the story.

I seriously hated MGS2's

Character1:"did you know religion blah blah?"

Character2:"Oh my god religion blah blah?!"

Character1:"yeah, 15% of blah religion blah bleh!"

One Thing I know is Kojima CAN'T make a great complex story.

Argh, not good news for me. I've been hoping that the story in MGS4, and ultimately the conclusion of the entire series would be as far as possible from the shitfest that was the latter half of MGS2, and keep going in the same direction as the awesome third part of the series.

Many a game/movie/whatever series has had a good plot for the most part, only to leave a bad taste in my mouth from a craptacular ending. Even the otherwise sparkling Metroid Prime trilogy managed to disappoint me like this, so hopefully MGS won't do the same.
