I feel like the best example to demonstrate why Nisekoi is bad isn't that far away, it comes in the form of Yamada and the 7 Witches. Both are harem shounen (in a sense...), Yamada's only about 10 chapters less than Nisekoi, but significantly more has happened plotwise. I stopped reading Nisekoi a long time ago because the 'comedy' revolved around the same 'this event where these girls can try to get Raku to notice them!' type thing every time, whereas with Yamada there's enough variety and weirdness that doesn't just involve some girl trying to score points with the main guy.
It probably helps a lot that Yamada, despite being himself, is a much better main character than Raku.
)the MC gives a go at all the girls before choosing.
