What are some positive comments to make when about a powerpoint presentation?

I have a few ideas (When doing a powerpoint presentation)
1) Use positive opening words(Nice, Passionate)
2) Positive content words( Impressive, Wonderful)
3) Positive discovery words(Discover found)
4) Positive closure words( Pleasure, enjoyed)

Hope this helps :)) 

What type of question is this. you can answer in your own opinion lol. Say, " That was interesting"

Fiscal policy because it refers to the use of government spending and tax policies to influence macroeconomic conditions, including aggregate demand, employment, inflation, and economic growth.
