Shadow and Bone

As someone who's read all the books in the grishaverse, I personally think this is an amazing and faithful adaptation. There are some minor changes to the characters, plot, etc, but I actually found that they improved upon aspects that were lacking in the books. I do think that it may be a little confusing for someone who is less familiar with the material, but overall the they do a great job fitting all the various stories together and having it all make sense.
