Anime themes can provide a series with a whole array of different atmospheres, from bittersweet to frightening, or heartwarming to chaotic. Some, if you check out their translations, are thought-provoking and provide new insights into the characters of the series. And some, of course, are downright silly, just like the anime they are attached to. After all, having a epic love ballad before a comedy show that has you splitting your sides just doesn't have the right effect. A little crazy is necessary from time to time, especially if there's a great opening video to along with it!
