About him hating MGS4, it's mostly down to the cutscenes. Halfway through the first long one (the helicopter scene with campbell, I believe), he got really impatient and kept saying that cutscenes are a thing of the past. He then kept commenting that the action sequences were too dull, the game's story is confusing, and the controls felt old. When he got to the next long cutscene, he gave up, and told me to return the game.
Before that, though, I tried to get him to look at Metal Gear Online. It liked it for a short time, but said that Gears was far better. So I took it and returned it.
Eh, well, some people just don't like the game. It is true that it doesn't welcome new players to the series all that well. There is a lack of explanation about what happened before, and a lack of introduction to the world of stealth either. It sorta feels like a game designed for the fans really.
