Them being very clear insisting murder was ordered by Putin while there is no proof for it, sure he was killed by someone's order but we will never know who ordered it. Also they painted him in way too good light for someone who was contract killer and secret spy.

I really liked 4 episodes format you can watch in one evening and show was interesting with not much boring scenes, though the inquest part and last episode was kinda redundant and lost pace. For me very strong 7, almost 8/10, obviously 100% rating is overrated and it's nowhere in par with Chernobyl for instance.

Also the concept is not very original and seem very similar to high quality The Investigation (2020).
