His Dark Materials is based on the book by Philip Pullman, and the trilogy which includes The Golden Compass, The Subtle Knife, and The Amber Spyglass. While I have not read the books, I found the TV series enjoyable. I am considering reading the books at a later time, maybe once the series is over.
The TV series is a combination of magic, drama, and fantasy. It has an incredibly high production quality (similar to that of Game of Thrones), but the story line is closer to that of Harry Potter (but still not very close). I think that it would appeal to a younger crowd, or people who are really into fantasy worlds.
I was also a big fan of the cast; there are not too many big names, although there are some such as Lin-Manuel Miranda and James McAvoy. Overall, the first season was both unpredictable and dramatic enough to keep me entertained throughout, and I was able to finish it in about a week or so.
There are 8 episodes in total, and they are about 45 minutes each. Season 2 was supposed to come out sometime later this year, but I am not sure if this timeline had to be postponed due to the coronavirus. I would definitely recommend giving the first episode a watch though and see if it seems like something you would enjoy.
