Your long rant has nothing to so do with the fact that the aiming hardly differs from COD. In COD it's L1 to ironsight R1 to fire, In MGS L1 to aim, R1 to fire, triangle is to ironsight. Pressing one extra button never bugged me throughout the whole game, and if really gets to you that much, then you should probably just play something else.
And with the fact that MGS also has a unique and awesome CQC system, running and gunning wasn't exactly the main point of the game (of course, still possible and easily done). So complaining about one more button to go into ironsights, which really isn't necessary because the normal aiming is just fine, is silly.
Also, what's with all the people complaining about the cutscenes? There's tons of good game inside MGS. It's not like every other second another cutscenes pops up. Lots of games do random cutscenes that don't really matter at all, like the camera pans to something of some importance (when you could easily find it yourself) and then simply brings you back into the game. Last time I checked, MGS doesn't have any of those. If there's a cutscene, it's important, or has something good to show.
