Afraid you're out of luck, then.
If you want your news spoon-fed, in the modern information environment, you're going to get one flavor. The internet made it possible to apply a broad spectrum of information to stories and have that spectrum made available to the world in ways that only news megacorporations used to be able to do. The bad news is that now you have to do some serious sifting. Sturgeon's Law applies just as much to the internet as anything else.
You point me to any example of an "in depth" story (I can't believe you used "Nightline" as an example), and I will quickly dig up a lot of things on the internet that the story did not touch on.
Also, it's safest to assume that even "in depth" stories have an agenda. You've got to use your own brain now.
