The cutscenes were the most horribly cheesy thing I've ever seen in a game. Maybe it's not knowing Metal Gear Solid (I never played the previous ones) but wow.
NO MARRY ME! 
However, as far as gameplay (all 4 hours of it), I thought it was great. That tornado musket was quite possibly the single coolest thing I've ever seen in a game ever.
It's good, but not the best this generation has to offer. I'd put it up there with Twilight Princess, Super Smash Bros Brawl, and Halo 3 as least deserving of the praise it got. Good, but not amazing, and at least (game mechanics-wise) better than the other 3 I just mentioned.
My list of best this gen:
Gears of War (cover system was a great innovation)
Dead Rising (for all its flaws, it was ridiculously fun to trash hundreds and thousands of zombies)
Super Mario Galaxy (brilliant level design and control)
Uncharted (I don't care what anyone says, or what scores say, that game rocks)
Resident Evil 4: Wii Edition (After playing this, I don't know how anyone could be psyched for RE5 and go back to slow and clumsy thumbsticks)
