I still say I'm warey of this.  Especially since it seems to be a TV film.  Either we'll get an unrealistic sunny happy performance, or we'll get one where every tiny ounce of darkness is over exaggerated to make it a shock film.  I did like a lot of what went down in the Mork and Mindy telefilm and I felt the Three Stooges telefilm was excellent, but other than that, they seem to be tear jerker scandal heavy half truths.
Now, I don;t have too much doubt that this will be a good film. But I want to see what focus will be taken from Henson's life.  And personally, I'd rather see a documentary, much like the Charles Shulz PBS American Masters one.  That was breathtakingly well done, IMO.  Much higher quality than a run of the mill documentary.
