Looks like somebody (Melis Ubueyev) studied their Pudovkin. Many gorgeous scenes with some strenuous camera movement, a chase even pops into the runner's POV as he's approaching yet another dangerously steep gorge. Certainly not afraid of contrast. Nice ending too. Not over-loaded with pro-Soviet story line. Though I usually feel many films are too long, in this case I think it could have used more fleshing out.
