Yeah, for once I'm kinda agreeing with Fistful (I know, I KNOW, ok???). Frankly, what I saw was an XO who was trying to make things entertaining for the 6000 or so 18-(however old the oldest person on that ship was) people on board the ship. High stress environment (warship in a war zone), lots of work, lots of DANGEROUS work, and you need to have some way of decompressing.
So long as all participants were willing participants, and watching said videos was not mandatory, I don't see the harm.
