I only things I can think of for are:
o To make sure the crawls are spelt correctly and use the right punctuation.
o To give feedback on the transitions. (I can give time codes)
o To keep track on the characters introduced or used in the show (like the clones) and make sure their stories make sense in the overall arc series.
Im confident I can do most of that my self but if/when I release a complete series package, it should have have the public seal of approval in my opinion 😉
