That makes total sense to me--and I love the guy. I was actually pleasantly surprised that anybody loved him too, since usually people are like "Why would you like Robin when you can have Batman?" And in the movies, of course, there's the (also *mainstream*) idea that Robin ruins Batman because Batman is cool because he's a loner and can't have relationships and certainly would never hang out with a kid.
But yeah, I've no problem believing that plenty of people find the character completely uninteresting--which is why it's good there's so many others to choose from.:-)
I almost assume, incidentally, that any references to how "everyone loves him" don't refer to readers or fandom at all, but are just a joke on the inner workings of the DCU where most characters do like him and girls (and guys) all agree he's hot no matter what their persuasion. When it comes to readers I always assume he's just got one subset of fans that really like him, probably a lot more who are neutral to mildly positive. Most people I've met who really hate him just hate Robin and the Batfamily because they think they reflect badly on Batman.
