Watched the series & there seemed to be one sort of generic tactical pocket knife, although a few people used it & one handgun which (of course) wound up in the hands of Dr Smith. Now they had some kind of 3d printer which is where the handgun came from. This was a collection of the planet's best & brightest crashing on a dangerous planet with hostile robots and vicious animals. Out of 15-20 people no one had the thought, "hey let's print up a dozen rifles or shotguns & some Bowie knives", & maybe give ourselves a 1/2 of a chance of surviving. The other thing that bothered me was they were on these advanced space ships that were highly computerized. In such an environment it would make sense to treat it as a "clean room" and yet everyone had lots of hair. The women had long hair, fake eye lashes & many of the men had beards. With all the computers you'd think everyone would have crew cuts to avoid a hair falling into some delicate part of the machinery. Somehow should we ever make a expedition to the farthest part of the Universe, I don't think it will be much like this.
