I mean it's a review for the prior attempts, as you Said. 
I agree. That's why I wrote 'so far' in the title. 

Is it?

The only part that refers to the documentary is that it’s "far from the first journalistic attempt to put an identity to the Nakamoto pseudonym". That might be a brief synopsis, but hardly a "critical evaluation of a piece of work".
