I totally agree. It looked exactly like I'd imagine a meteor coming down, too. However, that doesn't mean much. The meteor in the Armageddon movie looked pretty good to me, too. Tie fighters in Star Wars make sounds (in vacuum) just like I'd expect them, and the airplane crash sites in September 2001 looked pretty authentic on TV as well.
looked exactly like you'd expect
The problem is, all I've seen is stuff on TV and on youtube (and presumably the same is true for you), and neither source is reliable in any way. Nor is anything that "some super sapient expert" tells on TV or on the internet.
All you really know so far (and all they know) is that there exist some movies of "something" from an unknown source, with unknown editing, and unknown censorship. Some big smoke/vapor trail, and some glowing tail with a big flash in the lower third of the sky. Fine, youtube is full with all kinds of fake videos. Some seismologists might in addition have picked up some recordings that tell them there was indeed a big boom, ok, fine... but again, that boom could have been anything.
Unless you can lay hands on a big piece of molten metal with an "alien" composition that doesn't normally occur in Russia (or on Earth) in that form, that's about it, and for all it's worth, it could have been anything. Including a comet, a sattelite, a missle, or a smoke show for propaganda.
I've seen very similar, but of course smaller falling starts (long streak than a flash, then some more streak. I saw even more flashes some time). Of course I didn't see the smoke trails because of the night (but I think it's more of a cloud/jet stream than smoke or particles from the meteor)
