"String Theory isn't complete or perfect, and may never become either.
It may eventually come to be understood as merely a step, or more likely
a collection of important steps and some missteps that were still
inevitable in our quest for a unified theory.

"But branding it 'nonsense' is just ignorant. Whatever it is –
almost the whole truth, a glimpse of the truth, or a beautiful
non-truth which miraculously manages to come ever so close to
the truth – one thing it cannot be is nonsense. It's a
magnificent, shining edifice of such internal cohesiveness and
beauty that it almost doesn't matter if it doesn't describe
our own universe: the universe it does describe deserves our
attention and exploration.  -- Alon Amit

Why does that make it "better"?  The universe is what it is, neither
"worse" or "better."

“Relativity and quantum mechanics were not invented because someone
thought it would be a good idea for the universe to obey these rules;
rather, these revolutionary ideas were forced upon us by nature.”

The universe doesn't appear to be "smooth": not on the macro nor on
the micro.  Why would we expect it to be on the nano?  Field theory,
IMHO, appears to be an attempt to impose smoothness on an inherently
discontinuous reality.

So much for "smoothness" :-)
