(Spoilers inclusive)
Story 4/10
A boy named Raku, who likes a classmate called Kosaki and has a Yakuza group for family is forced into a fake engagement with a girl named Chitoge, whose family are the Mafia. Due to this and Raku's past a number of other girls join the harem and other characters try to expose the sham for what it is. From the start the story was as predictable as the Scottish Premier League. There was only way the story would go forward. This though was not a bad thing as a combination of good humor and amusing characters kept everything fun, though hackneyed plot twists didn't achieve the same interest they were expected to. The fun of the series lies with its very obvious slice of life harem antics. However like with any series of this type it grows stale and fast. The mangaka tries to liven things up with sporadic character inclusions and plot twists but it comes off as very weak. The humor is also only related to harem antics so its nothing special like Hayate no Gotoku. That's the main reason I stopped reading, it got boring. Of course this is not a general consensus as the manga is still going strong in Japan and has a high rating on most manga sites. On the former point though I think that Shounen Jump only keeps it there because it has attracted an Otaku crowd back to Shounen Jump and is thus a cash cow they can pump out like crazy. On the latter point, well all harems grow boring but some people like the characters to care.
Art 9/10
The mangaka's art has always been good and he's polished it even further with Nisekoi. It's very easy on the eyes, gives the girls a more slender moe look like Hayate no Gotoku than the buxom style of more ecchi series. He handles action scenes, romantic scenes and comedic ones well too.
Character 6/10
The main reason people enjoy harems is because they have a boner for one of the girls, or even multiple ones. This love evolves into rage on forums over which girl should get a happy ending. So the girls of Nisekoi are they any good? Well you get the full range, though the Yandere one is played as a little less Yan. There are two tsunderes, one nice quiet girl. No imoutos and Onee-san types up to the point I read but considering the popularity of these archtypes I expect them wander in at some point. Onto the guy, Raku. He's pretty plain, a good tsukkomi, damn lucky, a good cook and the typical nice guy that gets all the honeys (this doesn't happen in real life unless you look at least good enough for a model audition, just saying but that's fantasy). There's a few side characters that try heating things up constantly like Chitoge's butler, Raku's typical idiot unlucky buddy and Kosaki's best friend. Nothing overly interesting but a good mix for a while.
Enjoyment 6/10
This is sort of an aggregated scores as I grew steadily bored with how this series progressed. Simply put I enjoyed the initial comedy but that has a very one pattern style and so gets dull without much difficulty. If you enjoy slice of life and moe this is for you. If you want something funnier than there are a lot better options, if you want something ecchier there are better ones and if you're looking for a romance that is constantly compelling then I suggest Seo Kouji (he might be a massive ass but at least we hate because of how much we liked it at first). Nisekoi plays everything at a very for the whole family level and that takes a good setup of plot and characters and makes it quite dreary later on.
Overall 6/10
I won't pick Nisekoi back up from where I left off. Unless there is a major shift in the romance department I don't feel very interested in it anymore. Some people surely will and this series is tailor made for the modern Otaku needs... too bad I'm more into Fujoshi tastes (not the homo stuff though) or comedy.
