A harem with a twist
Nisekoi definitely stands out amongst other harem anime, and does so in the best possible way.
I went in to Niskoi with no knowledge but that in My Anime List's description; I had no idea of the hilarity that would ensue. I didn't even read the tags, so I had no idea it was a harem anime, I thought it was just going to be between the one the MC is forced to be with, and the one he wants to be with.
With a unique plot, and a diverse set of characters, Nisekoi manages to buck the trend which I have seen among other harem anime, and manages to deliver comedy on a level I haven't experienced since Watashi ga Motenai no wa Dou Kangaetemo Omaera ga Warui! Every episode had me laughing, which is rare, even for a comedy anime.
