Balanced, by definition, requires equal time pro and con.
Susan, I have found that the many times I have waited for an answer for the "pro"... the eventual response is always, "Pray and ask God if this is true. He'll give you a sign (burning bosom)." This is what it has always gotten down to when no one could answer a good question. I've also heard, "It doesn't matter what you show me. I give you my testimony...."
Moroni's challenge to us is to sincerely read the Book of Mormon and to ask God in the name of Jesus Christ if the Book of Mormon is true. Moroni promises that if we do these things, God will reveal to us by the power of the Holy Ghost that the Book of Mormon is true! I give you my testimony that I know by that power that the Book of Mormon is true.
That's always the final word! (Above came from an LDS website btw)
Not trying to be mean-spirited here, though it sounds like it, but this has just ALWAYS been my experience! I am always interested in reading good apologetics from Mormons, but it hits a wall fast and requires a huge leap all while ignoring glaring problems.
I wouldn't ask people to ignore what they honestly consider glaring problems toward any faith, including my own. If the Mormons could answer the comments and criticisms without requiring viewers to be biased (to ignore red flags vs be open-minded), then maybe there would have been a more equitable split of time. But they cut to the "testimony" just like the JWs cut to "wait on Jehovah".
Having said that, documentaries by PBS are interesting but often sound like they are the last word. They can be annoying sometimes. I take their shows with the approach that I can research on my own those things which sound incredible or biased. So I hope anyone, LDS or not, will relax and just review those areas which may --or may not-- be as PBS presented.
