So many things...But anybody at The Juilliard School or Berklee College of Music can tell you if you are good or bad on your musicianship...Anybody at the California School of Cinematic Arts or American Film Institute Conservatory can advise you on your future as a future Director...and anybody at the Pratt Institute can comment on your quality as an Artist.
Why do you dismiss the concept of Quality?
Can anyone else tell us that, or only certain 'gatekeepers'? Who gets to judge the amount of Quality in a thing, or whether something is Good for its Purpose?

"Quality" as in the amount of 'Goodness' something has?

An Axe is a bad Chair because it does not have the Qualities for (e.g.) sitting, but that is not its Purpose.
Were the folks that made PHM trying to make Art or Entertainment (or a mix of the two)? If PHM was made to be Entertainment, and people were entertained, was it not Good at its desired Purpose? Did 2007's Transformers have the Quality of Entertainment that it set out to have? Roger Ebert seems to have thought so.
