If beta reader actually help, then why are slush piles filled with horrible manuscripts, and even worse queries? Every blasted bad manuscript I see usually comes with a letter saying how much beta readers loved it. The worse the manuscript, the more likely it is that such a letter will come with it.
Beta readers almost always mean the blind are leading the blind. Stop listening to beta readers, do your homework, and learn to trust your own judgment.
And sometimes, just sometimes, the writer sucks dead dust bunnies, no matter what beta readers say.
Really, though, beta readers love every truly horrible manuscript and query I see. If you want freshness and originality, combined with great writing, it must come from you, not from beta readers who will do everything possible to make your query and your manuscript read just like what every writer they read does. This is great, if you want to submit same old, same old, but it's terrible if you want to be published.
