Let me start off with the good things about it: It has a very nice art style and sound design and I can tell a lot of work went in to make this aesthetically pleasing, however, this is about the extent of my enjoyment of this particular anime. I will say however that the art is of very, very high quality and is amazing if you're someone who enjoys anime which are very colorful and have an atypical art style.
My main problem with Nisekoi is that the main character is incredibly unintelligent, to the point where it was sometimes painful to watch him make such poor choices and ignore such obvious answers to his own inquiry. If you are the kind of person who finds themselves yelling at their screen when characters ignore the obvious or make unfounded conclusions then Nisekoi will probably damage your vocal chords.
At the end of the day, Nisekoi is neither here nor there when it comes to quality. It's a story that's been done before a million times, and unless you like the specific type of story being presented it might be worth passing on this one, because the characters just weren't memorable for me. They fit archetypes that have been done before and you can pretty much predict their lines in advance if you've seen a lot of comedies or harem anime. Nobody really "stood out" to me and no scenes stood out as particularly memorable.
If you don't mind the above and just want another comedic harem anime then you may enjoy this. I just didn't find myself able to get invested in it at all and often times it lost my attention completely.
