This show is exactly as it sounds, fun and a bit corny. After being bombarded with far too many scifi/fantasy shows that are unnecessarily depressing and take themselves way too seriously, I am very thankful to have found this show.
First and foremost, this show is fun. It's relatively fast paced and never gets boring. The cast of characters is very well rounded, and each has their own dynamic personality. The writing is quite good I must say, everything flows naturally without being forced, while both taking care of the character development and storyline.
On the weaker points of this show... the acting is not going to win anyone an oscar to be honest, but they still do manage to create interesting captivating characters. The visual effects are okayish, but there are definitely other shows that do that part better. Then it can definitely be argued that the show is corny, but to me personally that is honestly a positive trait, because the show doesn't take itself too seriously, and embraces it own corniness in an endearing way. But if "corny" is your kryptonite, you should probably stay as far away from this show as possible.
But if you are just looking for some fun, and are not taking everything too seriously, I can strongly recommend this show. At the end of the day, it just works. The combination of story, atmosphere, setting and characters all complement each other to create a world that is entertaining for the viewers.
The characters are quite diverse, and all - including the female characters - are treated as whole people. Which is very refreshing to watch.
Most of all, this show has a lot of potential. For the younger actors to gain experience and grow into the characters, and for the worldbuilding to expand and become even richer. There is lots of room for more stories to be told.
My only real regret about this show is that there weren't more episodes, and I truly and sincerely hope that they will get a second season, since this is one of the most fun shows to come on Netflix in a while.
