Thought it was interesting how they changed some major events and details in the adaptation, while still being quite faithful to the original series. I rather enjoyed watching the series, and I can't wait to see how things play out in future seasons.
Kind of wish they'd added more gadgets though, they were pretty fun to read about in the books, and it was cool to see Alex coming up with applications to the gadgets in various situations, but hopefully they have more in the future
