When Might We See the Next Perfect Netflix-DVD Movie?

Last Thursday I posted a list of 51 movies that received a Netflix-DVD perfect score of 4.9. For anyone who has experienced the joy of seeing a movie that they absolutely love, you know that those couple of hours of cinema nirvana don’t happen every day. If I’m lucky enough to run across a movie with a Netflix-DVD Best Guess of 4.9, that I haven’t seen, I know that there is a high probability that movie heaven has arrived. So the question is, “When am I likely to discover another Netflix-DVD movie with a 4.9 rating?”

Well, of the 51 perfect score movies out there today, here is the breakdown by month of how many 4.9 movies have gone into wide release for a given month:

Dec 14
Jun 7
Oct 7
May 6
Remaining Months < 5

It is not surprising that December is far and away the most represented month. Producers that are most confident in a particular movie’s chances of winning Oscar gold, release those movies in December. If we consolidate this list down to the three movie seasons, we see that Netflix perfection isn’t limited to Awards Season.

 # of  Movies # of movies per Month
Awards Season 25 8.3
Blockbuster Season 21 4.2
Dump Season 5 1.3

While it might appear that a perfect score movie is almost as likely to be released during Blockbuster Season as Awards Season, you need to keep in mind that Awards Season (Oct – Dec) is three months long while Blockbuster Season (Mar – Jul) is five months long. Based on the monthly average a perfect Netflix movie is almost twice as likely to be released during Awards Season as opposed to Blockbuster Season. Rarely is a perfect movie released in Dump Season. One of the five movies, Million Dollar Baby, went into limited release in December to be eligible for that year’s Awards Season before going into wide release in January. It was therefore released only technically during Dump Season.

So, now we know that the most likely time of the year for a new perfect score movie to be released is during Awards Season, particularly in December. Are we likely to see one released this year? Here’s where it gets tricky. From 1992 to 2010, at least one perfect score movie was released every year. Since 2010, we’ve had three released in 2012 and one released last year. Here’s the breakdown by decade:

2010’s 6
2000’s 15
1990’s 14
1980’s 7
1970’6 5
1960’s 2
1950’s 0
1940’s 2

Does this mean that movie heaven begins and ends between 1990 and 2009? No, the answer is more mundane. The answer lies in the statistical concept of the law of large numbers. Netflix needs a large statistical base of ratings for a particular movie before its model will assign it a 4.9. It is only with those large numbers will the Netflix model be able to confidently predict that you will love a particular movie. Of the 51 perfect score movies on my list, only four have fewer than 1,000,000 ratings – the relatively recent movies, The Martian, Argo, Lincoln, and the 1946 classic, It’s a Wonderful Life. The preponderance of perfect score movies between 1990 and 2009 has more to do with the fact that they are the most seen movies by Netflix raters.

To the question, “When will the next perfect Netflix-DVD movie come along?”, the answer is that it probably already has come along and it’s just waiting for enough Netflix ratings. Based on the results from 1992 to 2010, there is likely to be a perfect score movie this year, although it probably hasn’t been released yet (the one already released movie with a shot is Captain America: Civil War). In the mean time, watch those perfect Netflix movies from my last post that may have slipped by you. Experience a little bit of movie heaven while we wait for th next perfect movie to reveal itself.
