MGS4 -9 hours of cinematics, 21 hours gameplay=30 hour game. Good or bad?

30 hours seem a bit long for a type of game like this, but I don't mind. Anyways, the less cutscenes and more gameplay, the better. I do enjoy the story and cutscenes of MGS, but it gets a little boring watching countless of cutscenes after a while.
