My complaint:
I was amazed at how many different voices including commentators and the narrator pronouncing nuclear as NU-CU-LAR. These are supposed to be educated people speaking on behalf of the Science Channel. Please review scripts with speakers when commonly mispronounced words are in the script. It just makes the speakers and the channel sound stupid. You’re better than that.
Suggested solution:
Practice with the speakers and correct their pronunciation prior to filming OR change the script or speakers to ensure the correct pronunciations are used.
