Wait wait...I got it! NOW I know why Lost is a show you must watch before you die...
Because whomever you told to watch it would kill you, thereby absolving you of the guilt of suicide.
As much as I love Firefly, I can see how the lack of an understated overarching plot may have led to a tragically quick cancellation.
However, with LOST, not a single proponent of the series had a leg to stand on after the show was done. Honestly, if I watched LOST before I died, I'd want the time back plus interest.
The time I'd have wasted on LOST would have been more tragic than the cancellation of Firefly...
On the other hand, if I was GOING to die after watching the show, I suppose a case could be made for LOST, in that you'd live longer before it finished...but can such a tortured end to your days REALLY be called living?
EDIT: aww...poor Chris! Don't kill yourselves over these videos guys! We want you to stay healthy, esp so you can keep making more!
