Worth of product = (quality of idea) * (quality of execution).
An idea, on its own, is worth nothing (good idea * no execution = nothing).
HOWEVER...
Kickstarter (and other similar companies) are changing this notion a bit. Many companies have raised significant capital off of ideas alone, although producing a convincing video takes no small effort and the well-funded campaigns are usually run by people who have done their fair share of execution in the past. Capital does not equal profit necessarily, but it can if an excess of capital is raised.
