One that tells you the truth, not just "things that are true"?
For example, don't just tell us he said, and she said, and leave us to try to figure it out. Investigate until you know who's right, and why, and tell us.
I would rather prefer the exact opposite. News that tell me the facts and then let me figure out my opinion without mentioning theirs all the time.
I really wouldn't -- there are orders of magnitude more facts in the world than I have time to digest, so it certainly helps having a basis of analysis, even if sometimes that analysis is misguided.
