Nisemonogatari is a sequel to an excellent anime called Bakemonogatari, now this is not a light series, you have to pay attention and most of the time you wont get everything at first ( in fact after watching this episode I still have some questions about what happened between series but that will be explained later i think).
The story is about Araragi a guy who is/ used to be a vampire, and his little harem of girls he helped overcome some curses ( not a harem in the definition but there’s only girls in there so yeah).
The first episode of Nisemonogatari makes no sense if you didn’t watch Bakemonogatari ( and a lot is not even explained for those who watched ) making it a bit difficult for newcomers to endure it, there’s some pretty funny stuff in the episode but still a bland introduction.
All of the past season characteristics are intact the random color scenes, the static scenes with a lot of talking, the awesome animated scenes and a visual clarity rarely seen on anime (seriously even at 720p streamed it looked gorgeous) the lighting is awesome and knowing Shaft the Blu-rays are going to be much better since they always add stuff.
TL;DR: You should watch Bakemonogatari first if you want to watch and understand most of Nisemonogatari, but it looks like its going to be as great as the first season.
