I would actually argue that the way the Bible is constructed is an advantage and a blessing. Let's do a little comparative religion:
The Koran is supposed to be straight from God's mouth, through Mohammed. It is generally not subject to interpretation, but instead is to be memorized and obeyed. The major branches of Islam do not differ on doctrine, but instead the difference between Shia and Sunni is a question of who is in charge after the Prophet died. "Islam's" very meaning is "submission." Allah's word in the Koran is to be learned and submitted to. Far too many modern Christians and their secular critics consider this to also be the model for the Bible. It is not.
The founder of Mormonism, Joseph Smith, was troubled by the many competing interpretations of the Bible between different Protestant sects and wanted to have God's meaning nailed down, specified, and made consistent. So he wrote the Book of Mormon, and then added other "revelations" to that end. The end result of his additions and clarifications was that the Mormons, who consider the Bible only correct when viewed through the prism that he provided, feel they have the true interpretation of the Bible and the true version of Christianity. This means that full salvation is only available if you join the mormon church and subscribe to their doctrine. You have to fit the narrow mormon mold. I suspect too many protestants revere the Bible too highly to actually write their own additional clarifying scriptures, but there are certainly many who attempt to do the same thing through their "translations" or commentaries or other means. They want the "book God gave us" to be fixed, to be simple and consistent, and to mean what they want it to mean. To channel obiwan for a moment, they want the authorship question of Shakespeare to be finally settled for all time, and with the author they favor.
The Bible, with its beautiful ambiguities, and diverse styles and sources, is not so easily nailed down. It is a living document. It can be interpreted and drawn upon in different eras, by different cultures, and by different individuals. God's message can get to people wherever they are. There can be multiple christian traditions, diverse and wonderful, but still agreeing on the vital things. Nobody has to submit to one interpretation, and nobody has to fit themselves into one narrow mold of Christian.
And what's more, we have to use our brains. We don't just submit to the "one true interpretation". We have to reason out those apparent contradictions. We have to wrestle with the text, and put some effort into understanding it. We draw near to God as we do so.
I saw the LEGO movie with my kids yesterday, and I found it to be quite profound. The main theme was that sometimes it is good to "follow the instructions", but it is also good to let one's creativity loose--to explore what the blocks can do. There was a conflict between locking in the LEGOs into their "right" shape, and keeping them flexible and alive and open to new possibilities. I think too many people want the Bible to be like a book of LEGO instructions--a clear, step by step guide. That's fine, sometimes we need that. But the end result is uniformity, stasis, and death. God's message is alive, it is vibrant, the text is set but the meanings are constantly new.
