I always get a chuckle out of how much Giantbomb seems to hate Metal Gear Solid.
I for one and looking forward to MGS5 quite a bit.
From what I can remember MGS4 was universally loved around the GB office so I don't know where you're getting that from.
If you listen to the Bombcast, I'm pretty sure they have all been negative. They did like it in the past, but recently it's not been talked about with love. It's really weird.
I'm super excited!
