Can you provide some examples of documentation you do like?
While I can't ever remember reading some documentation and saying, "Wow, that was fun!", so I can't say there's any documentation I like. But I do find that the MSDN documentation usually gets me working, and not reading documentation much faster than others for e.g. Python, Java, JavaScript, CSS, my pedometer.
I read C# documentation several times a week. I do not like it.
