I originally thought nothing of it when a friend linked me to it.. then I watched the first level (E1M1).
Mind = blown

I like to see the whole game generally, but I have seen the speed runs about as frequently as I've watched full playthroughs (which is actually pretty infrequently ).  I'm not sure if you meant you weren't too interested in the video because you thought it wasn't 100%, or if you were just saying you generally have little interest in speedruns as a whole with this one being a pleasant surprise as a deviation from the standard.

The thing I like most about the speedruns for time (instead of completion) is the map summary view with all the monsters running around, jumping off things, and generally being pissed off that they didn't get to kill you, and that you showed little to no interest in them except as the occasional launch pad -- monsters have feelings too.

That was pretty impressive for what it was. I especially liked how the player telefragged a few monsters as they were spawning in. Likewise, killing that Fiend with the closing gate (which forced it to retract and allow the player to escape) was pretty nifty.
