Reading the description of those Russian bootlegs, they are over dubbed in Russian, so unless you speak it, they wouldn't be very fun to watch.
The Russians tend to do this thing where they take the original audio track and dub over it, so the original audio and voice acting will still be there, but you'll hear a voice in Russian talking over it. I've never seen that done in any other country I have been, other than in the instance of some documentaries.
