There are good managers that don't know what you are doing if you don't work in a pure software house. But they know how to work with that by setting goals, talking with you about it and when you deliver they start to appreciate you and your work even if they don't know anything about the details.

Hard to get those in larger corps though. It seems to always degrades to bullshit, no idea why. There are exceptions but it still seems to be a clear pattern.
