Rating : - Drywall
This video is overly simplistic and pretty much ignores any of the more challenging aspects of finishing drywall.
It does not address techniques for achieving acceptable finished joints on end-butted sheets.
It does not address "nail pops" or the advantages/disadvantages of nails versus screws.
There are no close-up shots to show a "finished" joint and how to achieve "even" or flat joints, on factory edges.
Sanding and sponge finishes are mentioned, but not in any detail.

If you are facing a serious drywall job and need to know the finer points of drywall finishing you will find this video lacking.
