I did not really mind the length and harem concept because the degree of chemistry and fun I have had with everyone of them. It felt more like City Hunter and it worked. Every facets and sides of our characters are explored and makes the milking work.
I get what you are thinking about Kosaki about the typical ideal Japanese girl. However, the author actually succeeds in making her character likable which is where Kishi failed. I recall that she really wanted Chitoge to be happy and did not want to see her all alone. She wants her friends to be happy and went to the US to help the female lead. Hinata sacrificed her friends to get Naruto. Unlike Hinata, she actually spends a lot of time with Raku and feels like a more believable relationship. The author doesn't mock the losers and help them find closure.
Edit: I had no doubts that he would chose Chitoge. Especially, the moment with the disastrous where they kept running running into each other. The moment where they were just started laughing sealed the deal.
Oh the ride wasn't itself wasn't so bad, it was only that Raku x Chitoge was already a forgone conclusion if you ask me. From the very first chapter and definitely if you've read the one-shot prior to the proper serialization. but the problem with that is that BECAUSE it's so obvious the journey to get there doesn't really excite me. My Main problems with with Love triangles, and harems actually is that it is pretty obvious from most who the mc would pick in the end. It's not balanced, and the favoritism is already towards the the love interest that the writer WANTS together with the MC, so the other characters are not there for anything besides pointless drama because again the writing already gives away the winner not matter how subtly it is done.
