Metallica is my favorite band, so obviously I'm partial. I agree they're not as sharp as they were years ago, but I still love to see them live, and will do so every chance I get. They have fun on stage, they're always changing up the setlist, and above all, the nostalgia factor. Most Metallica albums bring great memories.
