Detroit Metal City: Birth of the Metal Devil is a good introductory episode for Detroit Metal City, it features a good opening to show the viewer what it is all about whilst introducing the characters and the overall taste of the anime. For those that have already seen the anime then it wouldn't be much of a loss to dismiss this as it's just showing parts throughout the show, for new viewers I wouldn't be worried about being spoiled some of the best parts as it doesn't give away too much. If you're a new viewer then it is pretty good to see whether it'sthe sort of story and humor you would be into.
