Opposition to PCCs may have been part of it, but my understanding is that very large numbers of people weren't even aware that there was an election being held, and that many more felt they had no information about the role. Certainly that was the impression in my bubble, but you could well be right - unfortunately I haven't been able to find hard data on this. But I think the point holds regardless - local elections generally only get around mid-30s in turnout, unless they coincide with a general election, and I don't think people are opposed to having local councillors.
