Love this show
It's silly to the max. I love British humor so it is perfect for me. If you don't like dry and more slapstick type of vibe, this won't be for you. It's also filmed like the movie in a mockumentary style.
Nadja is hands down the best character. She is hilarious and 99% of the time the smartest person in the room. My household has gotten some fun 1 liner quotes from her.
I also like that sexuality is fluid and not ever addressed as a "thing". Since they live forever they have generally open relationships with any gender.
I don't like the common sense rating system. It is violent, has swearing, and has a lot of (mostly) implied sex, bit it's not meant for kids so I wouldn't say it has "too much" of those things. I also wouldn't say it has role models or a great message but if you want to find those types of messages you could justify your thinking.
