I know what you mean. Thinking of fans isn't so bad, but catering to them can lead to a weaker story. Dragonball... xD All of the series were really fun to watch, but completely ridiculous. Which is probably why it's considered the greatest battle manga. The story may not make a lot of sense, but it's fun to watch. It was harder to read though. I couldn't even finish the manga. It's fun, but I have to agree the story isn't that good.
Yeah, harmed are alright. I actually read a lot of them. The stories themselves don't usually bother me, as much as the indecisive endings. It looks like Monster Musume may head the same way. When I thought an end was in sight, it kept going. A lot of fun to read though. I haven't actually finished Netoge yet. I've been reading it online and I haven't seen the end yet. Even then, I never questioned who was going to end up together. It's really fun. I like how all of the characters are a little crazy. Except the female lead, who is really nuts. xD
