I have at last got round to this one!.. I both like and dislike string theory at the same time.Firstly the positive. I do not believe that mathematical singularities can make any sense in physical terms and an attempt to increase the dimensionality of the fundamental space is very sensible. Maybe an arbitrary initial approach is a good idea but this has lead to an explosion of mathematical possibilities without seemingly ever trying to come back to a physical reality and try to think how such string like structures could originate.As to the dimensions of space and time, it has I believe been adequately proved that the three of space and one of time that we see is the only sensible number that leads to a long lived universe. However we still have the fundamental problem that gravity causes our universe always to collapse and eventually form black holes. The only thing that prevents this is angular momentum in various guises this is the process that gives our universe its extended life.I feel,that looking at the physics and trying to understand the detailed effects of angular momentum conservation during extreme gravitational collapse is a far more sensible way to go. Looking at gravity working in the largest scales in the universe we see condensations in the form of galaxies (particles) and string like structures in the extension of clusters of galaxies so gravitational collapse in the large forms "strings" why should it not do so in the small.This returns me to state my fundamental belief of he way the universe is built. This is something that I have held since I was a child. Because matter and energy are convertible it is obvious that they are essentially the same thing and therefore everything is essentially bits of curled up space time and we need to study ways in which space time can be curled up.
