If you are new to this tragic case, then I'd recommend this doc. However, if you're already familiar with the details, you won't find anything new here. I've been aware of everything presented in this doc, hence, the 2 star rating. The truth of Russia's greatest unknown mystery is uncovered... is not. Imo, the film regards itself more towards the director's personal journey to Russia than anything else. If some sort of discovery was made during the expedition, it would've been worth the trip. But to trek halfway across the world just to visit the location of the tent did not hold my attention, nor did it impress me in any way.
