I love the first five albums especially RTL, MOP and S/T.
St Anger is worse than TLFR. Death Magnetic is ok, but not that memorable.

TLFR is great.

Death Magnetic I see it as a step in the right direction, but IMO it just doesn't have that much replay value that the pre-load albums had. I also go from love to liking the (re)load albums but to me there never gonna make a song like Fade to Black ever again. That's the shining light of Metallica's career. Just my opinion of course :D
