(Also... not a robot. Not a girl)
So true. I think if you are a fan of robots you'll like Janet, but, yes, you are totally correct according to the information revealed to me up to this point, and, I think she would thank you for correcting me. Janet plays her part so well that I didn't even notice she was any kind of attractive until ~ the time we get to see Bad Janet. I like Janet.
Yes. The cliffhanger, for my part, plausibly set up a Sisyphean loop that didn't necessarily need to be developed. Which I thought was perfect, because it struck me as a quirky little show that likely wouldn't get another season.
It didn't even cross my mind to let the episodes stop scrolling by from season to season. But, I think I can relate, in that, I had a similar feeling as what you describe in that I was hoping that things wouldn't get boring and routine and ordinary and/or one or more characters becoming... less likable. At one point I thought Tehani was going to start going overboard, but, all in all, I think everyone stayed even keel... kinda like TOS Star Trek, where, it's a team effort kinda thing and the team works because they stick to the formula that works - and there is chemistry.
Anyway, humm. I hope season 4 doesn't ruin anything for me, but, I'm betting it wont. Maybe it will. I'm gonna find out eventually but am in no real hurry. I kept seeing this show scroll by on Netflix lists and wasn't really in the mood for the subject matter at all but then I kinda wanted to see what Ted Danson was up to and then yahoo, what a unexpectedly entertaining gem.
