I like AFI best when they are going a mile a minute (e.g. Dancing Through Sunday) or when they are doing the ballad-esque songs (e.g. Morningstar). I really don't like Miss Murder AFI, which seems to be more of what this is. It sounds like mainstream alternative with a few oddities thrown in just for their own sake. My favorite tracks are Escape from Los Angeles and Begging for Trouble. It's more like 2.5/5.
