I already liked To Love-Ru before (when it was Momo) but this season is so good that I can not stop watching, even went to the manga.
The story is not about the wedding Rito and Lala (protagonists) as in the first season, but it shows more about the other girls. The girls won at least two episodes prominent with Rito, showing why they like him and each showing a different way of acting.
It is impossible not to like the girls, they do not have the same mode of operation as in "certain anime" that all girls like the protagonist and are rubbing it, they show that like the Rito of different and indirectly.
Despite being a ecchi he can have a good story without disturbing anything, showing the history and how each girl feel about Rito. Many people criticized for not having the same story of the first season, talking about marriage, but the story of Darkness has its purpose and is essential to the history of marriage continue to succeed .If you watched the first two seasons do not waste time and watch this that has the design better and best voices for sure you will see the anime otherwise and you will love it (or else love Momo as all hahaha.)
