First and foremost, if you started from watching the anime first and plan to marathon the manga, don't I highly recommend you not to. But if you are, go ahead I mean I can't really do much to stop you really. My advice is to start from the very start or continue where you left off from the Anime, you'll only be startled.

The series really got me riled up actually. To begin with, what I can say in terms of the story/plot is "Ugh, are you serious?" overall. There are TONS of turn-of-events. As the series progressed, it just gets more complicated, piling one after another. Quite a lot of cliché events to add to that.

Art is AWESOME, I've never really though of something like "that doesn't really look like __". Very good, crazy details for a weekly series.

Character is lacking in this series, specially character development. I'll give my thoughts on the MCs and other ones that are worth mentioning.

To start off we have our male leading MC, Ichijō Raku like a lot other characters are "dense". He's a smart student, very thoughtful & quite honest towards Chitoge. His love for the "Promised Girl" is admirable, he hasn't thunk much what he would feel if it was Chitoge or Marika but always though that if Kosaki was "her", would be very happy from the bottom of his heart. Nothing much to say about him, his pretty ordinary I'd say.

Kirisaki Chitoge, tsundere or not? Personally I think how much people like her is over exaggeration. I'm not sure if I hate her overall but I definitely detest her personality. She's full of pride, totally not feminine (for the most part anyways), violent, rude and abusive. I really don't like her act of tsundere if she's considered one. She also doesn't respect people much unless she has a good relationship with them, examples of this is physically hurting Marika just because she "pisses" her off. Marika is STILL the fiancé of Raku and she should respect that she and Raku are only pretending to date because of their family's relationship. She really needs a huge character development, I don't see why her attitude has to be like that.

Onodera Kosaki, the cutest person in this series in my opinion. She very thoughtful of others just like Raku. She misleads what Raku's doing sometimes even though he might be doing this and that for her. She doesn't have very much self esteem but I think that's another adorable side of her. She's pretty much the ideal girl of Raku. Just like Raku again, she wishes that the boy she promised with long time ago is him.

Tachibana Marika, my favourite in this series! Personally I think forcing your love to somebody is very wrong, specially when the other person don't seem to feel the same towards you. In this case though I HIGHLY think Marika deserves Raku the best. Marika's engagement with Raku is something that their parents agreed upon but that's not the reason why she's currently heads over heels for Raku. She treasured all her memories with Raku all those years and haven't forgotten about them, even coming to as trying her best to be his ideal girl, growing her hair, changing the way she speaks etc. Raku also thinks that he can't believe such a beautiful girl like him, which in my opinion is a huge I mean he thinks very negative of Chitoge most of the time. Oh and of all she's been the only one to kiss Raku, even two times!

Tsugumi Seishirou, I'm not sure what I really think of her, I personally don't like Seishirou chapters. I do know that I like her more than Chitoge and that she's more cute than her. She's so obvious with her tsundere attitude.

Miyamoro Ruri, she's hilarious and has very good common sense/awareness.

If you don't practically like enjoy mystery series but are good at inferring, you might this one. The comedy on this series I would have to say aren't really one of the best, it's mostly Chitoge being violent other than that embarrassing moments and Ruri appearances. There aren't that much ecchi in it but when there is it's quite enjoyable. I personally really don't like the fact it's shōjo I think it ruins it.

Overall your in a bitter sweet ride with Nisekoi but before you realize it, it's probably late to back down and drop it if you want to since you wanna know how it's gonna end up.
