Hmm...I think they just had a lot to fit in as they are piecing everything together. I still think that it would be better with more gameplay but there is still enough imo, especially if you are aiming for no alerts or continues. I think a lot of people like the cutscenes as well abeit mainly the fans but Kojima stated that 4 will be aimed at the more hardcore MGS audience. Best thing to do really is to learn the story then just play it with skipping the cutscenes. Personally for me I enjoyed all the cutscenes, but am a bit of fanboy and was well into the story and the character depth.
