Here's the difference between Art Bell and George Noory: Passion, credibility and sincerity.

Noory is simply following a script and isn't genuinely engaged. He doesn't believe half the things he presents on the program, although he pretends he does.

Art Bell was genuinely inquisitive and curious about everything on his show. As such, he presented things with intellectual honesty and passion that would result in deeper questions and probing Rather than the surface level perfunctory nonsense that Noory spouts.
