He made some very good documentaries and taught me a lot about the sciences. It will be ashamed if the allegations are true but if they are he should be made to account for it.
I enjoy listening to his podcast Star Talk. I prefer the episodes involving astronomy and physics, but he is always humorous and interesting no matter the topic!
Neil Degrasse Tyson is one of my heroes. An astrophysicist who was mentored by Carl Sagan, an atheist who is not a jerk about it. It's hard not to love the man. For a treat, check out his appearances on Stephen Colbert's show. They have a lot of fun together.
