"Alex Rider"

If you are looking for a faithful rendition of the books, you are out of luck.  There are dramatic changes from the novels.  Like most "book-to-TV" transitions the lead character is older, the story is much darker, and, because this is visual, the violence more visceral, the losses more emotional.  Beyond that there are substantive changes to the book narrative.  Events are rearranged and characters are heavily re-written if not utterly new.  There are contemporary comments ("Social Media allows people to take your rights and have you thank them for it") as well as AI and cellphones integrated into the tale (which didn't exist when the first books were written).  All that being said, this series is good.  Really good.  I blasted through the first two seasons in three days.  Action is well-paced and engrossing.  Storylines have nice twists and the cast is, like all British productions, outstanding.  Unfortunately it's on "Freevee" which means that commercials (ones you can't speed through), interrupt the storyline.  But it's good enough that even though my attention tends to wander with the breaks, I focused right back in after each.  The only other complaint, which is minor, is that the entire cast is British -- with some actors playing Americans, but unable to really nail the accent.  It's okay.  American actors have been butchering British accents for years.  Turnabout is fair play.  A special shout-out to Otto Farrant, who encapsulates the heart of a lost 16 year-old even though he is more than ten years older than the character.  He and the rest of the crew get snaps for VERY physical committment to the show.  It's clear Mr. Farrant is doing most of his own stunts and they are impressive.  Can't wait for season three.
