Have a friend who just had crown molding installed in his home, in the
living room the ceiling is rectangular, but the height at the rear
wall of the house is 8ft, the height on the opposite end is like
15-16ft.

The "expert" installing the molding told him it was IMPOSSIBLE to
cope/miter the corners and he instead installed decorative blocks at
each corner

Bottom line, was the installer incompotent and this was doable, and if
so, how is it done. If it is NOT possible to miter/cope those joints,
is the decorative blocks the ONLY solution or are there other options.

Frankly, I think the decorative blocks look like ****

Depending on the situation, it can be done. You mount the molding in
relation to the ceiling, not the wall. The crown where the sloped ceiling
meets the wall at more than, or less than, a 90 degree angle will be kicked
out of plumb slightly to match the angle of the ceiling. Some planing will
be required on the back side of the crown where it meets the wall.
Confused yet? I think I am!
