Hum, I don't think that anyone doesn't like ESFJs. In the real world, they seem to belong to the 'most successful' types (in a social sense); they always have a lot of friends, lot of success with the other gender, people find them funny, outgoing and pleasurably "normal". They have a good sense of what is accepted, so they behave and look as acceptable as possible.
And that is probably the reason why it seems that people here hate them, because they are often the opposite of all mentioned above.
This is my general view of this, but if you want my personal opinion, I don't like the 'drama queen' nature of some ESFJ girls I know. When I was still in middle school and high school, it seemed to me that they often cried and pitied themselves for absolutely no reason (their social position was like, million times better than mine, and I didn't make a thousandth as much fuss about it as they did about their (in my eyes) petty problems). Also, now in university I've made an ESFJ friend who initially seemed very friendly, out-going and light-hearted to me, and we connected pretty well last year, but since we became flatmates this year, she's changed, and to my dismay she never stops nagging, she is extremely concerned about mundane things I don't give a damn about, and overall she's become very bitchy and unpleasant. And I confess that my experience with ESFJ males is even less pleasurable.
But still, there are definitely some ESFJs out there that I like, like the classmate of mine who doesn't nag or 'drama-queens' at all, just the opposite, she's extremely good-natured, jovial, sanguine and always brings good mood everywhere she comes. In the end it all depends on individual characteristics of the person, not really their general type, so don't worry about it too much.
