My taste in anime has changed a lot over the years. In 2006, I started out watching series like Ouran High School Host Club and Haruhi Suzumiya. But lately, I've been into series like Oyasumi Punpun and Aku no Hana, which are both dark and psychological series compared to the former.
Currently, I'm diving into Neon Genesis Evangelion, which is considered to be one of the most influential and controversial anime of all time. It's an anime to be seen by all, or else you really haven't seen anything yet. Evangelion takes place in 2015, where war machines called Angels, have appeared in Tokyo for the second time. Only a handful of teenagers are capable of fighting them, all born 14 years ago. Together these teenagers work with NERV to destroy the Angels before more harm comes to Tokyo.
Another series that I have been enjoying is Nagi no Asukara, also known as a Lull in the Sea. It is currently airing, so it's not a completed series compared to NGE, which aired from 1995 to 1996. Nagi no Asukara takes place in a beautiful underwater world where some humans live in the ocean and some live on land. Mysterious things lie ahead when the sea and land dwellers meet for the first time.
Also, the 2014 winter anime season has just started airing so I am looking forward to new series coming out: Chuunibyou demo Koi ga Shitai! Ren and the new edition of the Sailor Moon series.
