Inspired by gregorum's post concerning issues with startrek.website, which is ironic as lemmy.world is a bit glitchy right now and isn't letting me upload and had to use my alt here.
I'm watching the first bit of that episode now, and in fairness, at least they attempt to sort of justify it by saying it's just that the Borg assimilated species with better medical technology and that their ability to revive drones is limited to only up to 73 hours after death.
I don't have a copy of the JJ movie conveniently to hand at the moment to check (I never bothered to obtain a copy because all the plot holes piss me off), but I don't recall them even bothering to do any hand-waving to limit the scope.
