I'm somewhere between Terry and PSac on my opinion of Bart Ehrman. When I read his work, I see the scholarly craft and attention to detail. As for the title FORGED, he and his publishing company have to sell books. The title grabs attention. It may be enough to cause someone to pick up the book and read the synopsis to see if it's for them.
When I see him speak I get a different impression. I've watched his lectures on YouTube and I don't like how he comes across. He lacks poise, polish and sophistication. He seems like a nerd that was bullied one too many times but now has the power of a microphone and a PhD. He tries too hard to make his point with "can you believe this stuff?!" gestures and facial expressions instead of letting the points make themselves. When he gets ready to set up and argument, it just feels cheap, even though he is usually right.
Just my opinion.
