The dialog is insanely hilarious! Every single segment, no matter how small, has humans speaking in ways that humans would be speaking if humans spoke everything perfectly. No "ahhs" or "you knows" or any verbal miscues. This only applies to the liberals though. The conservatives or more accurately "targets" in the show are absolute idiots who obviously can't think. Sorkin writes such that his characters sound like geniuses speaking with retards. With a cadence that reminds me of an old bit Johnny Carson did years ago with Jack Webb.
The funniest thing is the seriousness of everything. Everything is such a big deal. It is one very long OMG! Which is amusing because they do their "news show" then all go home. Which is kind of silly considering the "gravity" of everything they do. They are saving the entire planet but just not all the time. LOL!
The bottom line is that "The News Room" is nothing more than a liberal circle jerk that is very transparent unless you are a moron.....
If the dialogue sounds unlikely, it's because it's been recycled from all his earlier shows.
