This is on free streaming from various Amazon sources, such as IMDB TV in the USA.  They did a really good job with the show.  This is based on the Alex Rider series of novels, which are over the top teen spy thriller type books.  The show (as the trailer shows) is likewise over the top.  They did a nice job here on season 1 in basically merging the first two books and giving you enough to show respect, but mixing it up enough to still throw surprises at you.

Season 2 is also out, but I haven't had the time yet to dive on it. I'll post something more when I do.
