Why is there so much hatred towards Naruto on the internet?

I wouldn't call myself a "hater", but I started watching Naruto in December 2013. Before then, I've heard bad things about Naruto, people saying it sucks and stuff like that. I watched one episode of Naruto and a part of a movie (the first one with the ice land thing lol) before I met my friend that got me into Naruto. Anyways, because initially I thought Naruto was supposed to be a bad anime, I never really gave it a chance. I really thought the whole anime was going to be a lot of ninjas (or guys acting like ninjas because they don't look like ninjas at all) just tree jumping.
Even when I saw the first subbed episode in December, I was still kinda skeptical if it was good or not. But because my friend really wanted me to watch it, I did and I liked it....a lot...the first episode was one of the best episodes of the anime actually (and it had no Kakashi, amazing) xD So, I'm guessing most of the haters are just people that never watched Naruto and they just hear its bad, and think its bad.

I have three possible reasons.

1.) The popularity. Because it's the most popular of the "Big Three" (Naruto, Bleach, One Piece) and some people think other animes deserve more attention. This is similar to the reason people might dislike Hatsune Miku. She's not bad, it's just that some would rather have others like Rin/Len be more popular.

2.) The plot. If you take all of the little details out of it, it's a bunch of uniquely dressed ninjas fighting eachother with at least one flashback guaranteed for each fight scene. I hate to say it, but there are other animes out there with better plot. Maybe some people that hate on it don't like the shounen genre in general and choose to hate on Naruto since it's a really popular shounen.

3.) The fans. (I'm referring to the obsessive, stubborn fans.) There are fans of Naruto that are the ones who have probably not dug deeper into anime than the Big 3. This is totally fine by me, but sometimes they get annoying and say things like, "Naruto is the best anime ever, and you are stupid for not liking it!" When they do this, some people argue against them, making it seem like they don't like it as much as they might actually like it.

I'm not a Naruto hater, I just know a few reasons that haters might dislike it.

Tsk. Because they're haters with no life whose only purpose is to hate on what's popular. Or because they have no opinion of their own and only jump on a bandwagon to appear "cool" but are actually lame. Seriously, I don't know what's to hate on. The story is decent to say the least, (most) of the characters are great and have depth, it has character development, great OSTs, fights, etc. The 'problems' people may find in it is only because Shonen Jump requires those things (ex: flashbacks, powerups, etc.) But Naruto does it beautifully. It's a pretty good anime/manga. I'll NEVER understand those haters really. -_-'
