Yeah, I'm one of those that will complain. I have no shame at all. That's just my opinion, just me venting.
Are all Mangaka afraid of romance, shy, or maybe just stupid? Sorry about that last one, but I'm really tired of these shitty/incomplete/nonsense/irrelevant endings. Personally, I prefer some generic "Disney" happy ending. It's not worth spending time reading manga to find real life (but "5 Centimetres per second" is an amazing animation/movie).
I think it's important to reach some kind of ending, be it a good or a bad one. Take "Peach Milk Crown" as an example. That's how to be a brave mangaka.
Unfortunately this manga turned out to have a generic, poorly developed, plot. At the last chapter there was nothing more important than showing this fucking cliche where he falls on her and kiss her instead of breaking a teeth?
