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

Well fantastic to know it's got 9 hours of cinematic ;) In retrospect to the past games thats great news indeed ^^ To be honest I'm in the same boat as the OP and totally wouldn't mind a 50/50 split :D But I LIKE Kojima's over the top style ^^ so maybe that's just a few of us. I'm really curious as to how they're going to have 21 hours of gameplay though o.O; Thats pretty massive for a story driven non/rpg/non puzzle type game.
