Whether the new rules are successful is still debated, since 2005's Grizzly Man, a documentary strong enough to appear on many critics' top 10 lists was not nominated, and did not even make the Academy's internally distributed top 15 list. Grizzly Man's exclusion was actually revealed as the result of an Academy rule disqualifying documentary films that are constructed entirely out of archive footage. However, Grizzly Man included new interviews and other footage shot exclusively for the film.
There is debate over the role television distribution should play in the selection process.
