While I was in another country a few years back, I was stuck between seminar's and had access to piles of Russian Martial arts videos, from Russia, in Russian. Then some translated, then the usual the USA versions. This included home grown Systema and USA/Euro versions of Sytema. Some of this footage was seminar footage from Russia. I saw several two day Systema seminars filmed in Russia.
I watched them and have some conclusions
1) The best parts of them are found in the best parts of other systems. This I have found to be universally true with all martial arts and why I now can longer jump both feet in any program.
2) Just behind the next curtain of a lot of Systema is a lot of voodoo, magic crap. Not unlike many Silats and well, hell, psychic knock-out stuff found here. Snake-oil salesmen material! This immediately turns me off.
3) Some of it is really...well...slinkly...the defenders are slinky, that ATTACKERS ARE SLINKY. Myth of the duel...slinky meets and fights slinky. Inside all of this slinky-ness, I collected just a handful of practical deflections I thought had good potential. But the overall slinky-ness was a big turn-off for me.
4) Russian Sambo, not Systema looks a lot like hard-core ju-jitsu, and good quality ninjitsu. Ninjitsu will always be tainted by the turtles and kids-attraction sell-power.
5) Where its good, its good, where its bad it sucks. My "okay" meter needle is on the negative side. (this is where I begin to hear the classic line - "Poor Hoch, if you would just train with ______ and stay long enough, you'd discover the truth."
I a registered, jaded practicalist. I'll never understand the fad hoopla of anything.
Factored into the system-selection process, people ponder these systems because of the fad, flavor, look or appeal. All martial arts are this way, Japanese, Indo, FMA, Isreali. Everone has their own zoot suit, hairdo and lingo and well...wake me when its over.
When you become jaded like me, you are just hunting around from another tactic, and could give two shits and a balloon where it comes from.
