The movie is entertaining and instructive, but to label it, "based on the true story" is misleading. Most of the story cornerstones are pure inventions and have nothing to do with the truth. Many of the key events in the film never happened in reality. This is the biggest shortcoming of the movie-it is a lie.
Another weak point is that the story remains fuzzy. The protagonists never make it clear what exactly they are doing and why. Thus the movie remains superficial and never really explains what is happening.
The technical computer and internet action details look as if the script writers were completely clueless and just sucked nonsense from their fingers. They seemed to barely know what an IP address is, but onion routing was alread way beyond their understanding. For a movie that is centered so much on the internet and the darknet one would wish for more precision in such details.
Apart from these shortcomings the relations between the protagonists are gripping and interesting to watch.
