I must say, I've never liked cutscenes as much as I like the ones in MGS4 - and it's easy to see how Kojima filled a dual-layer Blu-ray disc (50gb!). Saying that, though, the game itself is in no way lacking. I've been playing for 12 hours, and I reckon I'm about halfway through the second act. It took me about nine hours to finish Act 1, and I do believe there are five Acts, so it's a pretty lengthy game. Add in the myriad different ways of playing it and, well, you get the picture.
