You think this would be common sense but you'd be surprised how many great series are overlooked because of the photo or a poor description. Never judge whether to watch an anime by its description or picture. As someone who has been watching anime for multiple years and has seen several hundred series I can appreciate when an anime has true legitimate merit.
I have watched all of these to completion and can confirm they are certainly worthwhile viewing. You will need to research some series on anime review sites as IMDb has limited information on anime. An anime can only be considered for this list upon being completed, if you want a list of good ongoing anime please go somewhere else. I took many as you can see by my description, this is not a list for most popular anime only. I didn't take just one factor into consideration. Some of the qualifying factors taken into consideration for a series being deemed great are, entertainment value, popularity, lasting appeal, quality of writing, originality and significance to the medium of anime. This list of 'Top 100 Anime Series Of All Time' will feature what I consider to be the 100 greatest anime series ever made.
