Are You A Picky Reader?

Hey fellow readers! I've been in a bit of a reading/reviewing slump recently so I decided to do another post. I'm not sure if I've posted on this subject before or not, so feel free to let me know if I have. But recently I've been reading a lot of novels that have too much of a certain issue and not enough information, or too much information and not enough action.
So, that got me thinking, am I a picky reader? I don't know. I hate to think that I am. The novel I'm reading right now is very romance filled, and sometimes it just seems to drag on, and doesn't give too much elaboration on what happened in the past. And in some novels I've read in the past, there seems to be less romance when I want it, and more of a history lesson than a novel.
Maybe I'm not making too much sense, but when reading a novel, do you as a reader sometimes get frustrated by not having enough of either romance/ or an explanation / or maybe you're just craving more action? Do you ever get frustrated with the author and think, why did they do that? Do you ever have imaginary arguments with the author or the characters involved in the novel?
Sometimes my brain gets picky and thinks that too much of a good thing can be an overkill in a novel, and too less of one thing can wreck a novel too. And lately I've also been reading a lot of popular books that people really seemed to love, but I'm the odd one out and didn't love it as much as others. Has that ever happened to you as a reader? Like you feel like you're the only weird one because everyone else adored it? With novels like those, I usually tend to not post my reviews in other places, for fear of backlash. Anyway, I seem to be blabbing on, so I think I'll stop for now, and would love to read some of your reactions to these situations.
