I don't understand

Different people like different genres of anime.
Lucky 星, 星级 is 'a 日 in the life' kind of anime, and some people find that boring. I loved the 日本动漫 cause I related with Konata.
But, I also 爱情 Psychological Horror and Action anime.
So, it really does depend.

I'm not sure. I haven't really watched the anime, but maybe it has something to do with the character 设计 and/or development?

I hate it because I found it boring, it wasn't funny at all to me, and all the characters annoyed me.

Personally I liked the anime, but the reason a lot of people don't like it, and a lot of other slice of life/school life animes is usually because of one of the following reasons...

1.The Plot. there usually isn't much plot beyond just doing 随意 almost daily things, people who prefer action,horror, etc. may find them to be incredibly boring. Let's face it in Lucky 星, 星级 there wasn't really a long lasting conflict 或者 real plot development beyond the girls problems in school etc.

2. The characters, from what I've noticed (but not always true) characters in school life/ slice of life 日本动漫 usually don't change a whole lot 或者 have seriously interesting backgrounds/magical powers etc. that need explaining. The characters are usually meant to be very relate able and not entirely far-fetched as other 日本动漫 characters are. Again someone who likes action, mysterious characters, characters with special powers, 或者 deep character development probably don't like much of this genre. A genre of which Lucky 星, 星级 is a well known and A+ example of. For many people simply "being funny" isn't enough of a character to justify watching a whole 显示 for them.

Like I 说 before, personally I liked the show, and I know a lot of others don't. What a person needs to understand is that everyone has their own opinion on a show. hope this sheds some light on your question. I like the 显示 so I can't speak from personal experience, but I do think people who don't would agree with me.

I don't hate it. I just found the 日本动漫 really boring. I don't really like slice-of-life 日本动漫 all that much. That's a factor of why I didn't like Lucky Star. I couldn't find myself liking Konata. She wasn't funny and honestly should really focus a bit 更多 on her schoolwork over 日本动漫 and 日本漫画 instead. Sometimes I wonder how she graduated to high school. (If she is in high school currently.) I don't really find the other characters all that interesting to be exact.

Because a lot of people find it annoying and boring. Myself included.

personally, i thought it was really cute and i like it :)
but different people have different tastes so...yeah
