vampire knight

explanation:

its a two season anime series filmed in 2008, but the film production is great.   its dubbed in english, and has closed captions if that isn't good enough.   its very romantic and sort of weird when you find out who the main characters are at the end.   very very dramatic, but in a good way, and never gets old.   i've watched it over and over again but it still has not gotten old.   you'll love the night class.
