TOS can only get better with time in my opinion. The flaws are not really an issue with me. TOS has that cool 60's grainy
look that can't be duplicated. In that respect, it's impossible to produce a new ST series, or a TOS themed movie with the same quality, because that quality is a product of it's decade.
Trying to duplicate the TOS is like trying to make a new Humphrey Bogart movie. It's impossible.
