What makes death note a great anime

Death note is on of my favorite anime which is filled withsupernatural, psychological, action and drama.I did never consider an anime good without fight but after watching death note I realized that fighting isn't necessary and I'm not gonna spoil but I would say it was a master piece and if L finished the game of light then it would be considered as the greatest anime ever. There are also some similar anime like death note i suggest you guys to watch them
