When it comes to Nikola Tesla, there are usually two camps: those who have read his books and texts and greatly admire his empathy and humanistic vision, including his work on aetheric energy, his theory on dynamic gravitation, and possibly things like the FluxLiner craft with Otis Carr, or even that he was part in Philadelphia Experiment along with Albert Einstein.
And then there are those who have little actual knowledge or clue of him and his inventions and discredit him as an idealistic nut.
Being familiar with the story behind Nikola Tesla and spending the past years into his life, I can tell you this documentary is biased and prejudiced at presenting only a skeptical and close-minded perspective of the Serbian Wizard.
Furthermore, a lot of the claims made in the film are inaccurate, or fuzzy to say the least. For example, there is misrepresentation and lack of research into his Colorado Spring experiments where he envisioned wireless transmission of electricity to the earth, not by sheer power, but by resonance and high voltage (not high amp).
So while I embrace the adage that no publicity is bad publicity, meaning that any representation of Tesla is better than having none, I hope the audience is curious enough to dig further than the claims of a lone, lunatic inventor whose technology became a pillar of our modern civilization in the last and current century.
My recommendation is go watch The Prestige by Christopher Nolan who does a much better job at capturing the mystery and visionary characters played by none other than David Bowie as Nikola Tesla.
