I saw this on Netflix and enjoyed it, it's a mystery that I was vaguely familiar with but this did go into quite a bit of detail about the main theories. I have to take away one mark for the way that they randomly label the theories 'theory 231' then 'theory 70' and so on without in fact listing hundreds of theories in total. I'll take away one mark for the 'exploding mosquitos' theory - really????? The final mark I'll take away for NetFlix only showing the first 43 mins of the 49 minute doc, the whole film can be seen on YOuTube with the last 6 minutes included - those 6 minutes are important as they address the fact that it was nearly as bright at night as during the day for three whole nights across much of Europe in the wake of the Tunguska event, people read their newspapers at night without the need for artificial light!
The only two theories worth a damn are the theory that it was a comet which exploded before it hit the ground and the alternative one that the volcanic pressure below ground was so high that the crust cracked and gas burst through the Earth's crust and ignite but that the pressure wasn't great enough to force the magma itself to the surface to produce lava. The first hypothesis seems more likely as the second one doesn't seem to correspond to anything that's ever actually occurred anywhere else on the Earth, though I may be wrong on that.
