Barely a science fiction except for the plot and a few rare strange things here and there.
Basic common sense things missing, actors are always fresh, wearing new clothes, survive just fine not feeling hungry for extended period of time. Some character development is the only thing that is not so bad. Strange unnatural emotions such as not being grateful for someone saving your life! Overall not very entertaining, if you have nothing else to do and you are extremely bored you can watch it in 1.5x speed. Don't let "japanese" mislead you, they can be bad too :) Highly doubt there will be a second season any time soon, if at all.
