String! Theory! What is it good for ?!?

I cannot pretend to even begin to understand the mathematics behind string theory, but can you answer this simple question for me cavediver?Using quantum mechanics as an example, I think it is safe to say that there are some outlandish assumptions (or at least outlandish implications of some assumptions) inherent to quantum mechanics, and yet it (QM) is used as a tool to make extremely accurate predictions. This does not prove that it is an entirely complete and accurate model, but it seems fair to say that this demonstrates that it has to be right on some level.

• Assuming the above statement is an accurate assessment, can the same thing be said of string theory in any sense?
  ​
• If not, what is it that makes string theory so worth pursuing? Is it the potential to marry relativity and QM together?
