Although I know all the cool kids use Netflix, I've been a customer of Blockbuster Online for awhile. I have a hopelessly long queue, both movies and TV shows. I can, of course, move things up and down in the queue.
So I did the Statistics 101 thing, aided by some Perl web-crawling scripting and Gnuplot: a scatter plot for each movie in my queue that had both an IMDB rating and a RT rating. (click to embiggen):
I've seen worse data! They look kind of correlated, so let's also put in the linear best-fit line:
Looks almost like science! For anyone who knows what "correlation coefficient" means: it's 0.79 for this data.
Some miscellaneous observations:
The data should not be taken to represent anything general
about IMDB and RT ratings. For example, I've either
already seen, or decided I don't want to see, very high-rated movies.
Similarly, there aren't a lot of dreadful movies in the queue.
So the movies in the data aren't necessarily representative of movies
RT advertises their "Tomatometer" ratings prominently, but I
used their fine-print "Average Rating" instead. The Tomatometer
is (roughly) the fraction of critics who liked the movie; the Average
Rating is more comparable to what IMDB does: each movie gets a score
Fun facts: although IMDB rates movies from 1-10,
there are only two
movies at IMDB with ratings greater than 9: The Shawshank
Redemption and The Godfather.
And there are only 38
movies with ratings under 2. I'm pretty sure the lowest-IMDB-rated movie
I've ever watched is Epic Movie, which
has a 2.2.
The movie up there in the northeast corner of the plot is The
General, a silent Buster Keaton movie from 1927. It gets an
8.3 at IMDB and an 8.8 at RT.
I'll move that up in the queue.
Down there in the southwest corner with IMDB ratings under 5.5 and
RT ratings under 5.0: M. Night Shyamalan's The Happening;
The Mummy: Tomb of the Dragon Emperor; and Balls of Fury
(the ping-pong comedy with Christopher Walken). Maybe I shouldn't
bother with those, at least not until I've seen every other better
Somewhat interesting are the outliers: Eagle Eye was relatively
by the critics (RT
rating: 4.6) but the rankers at IMDB didn't think it was that
bad, giving it a 6.8.
(In the same boat: War, with Jason Stethem and Jet Li, 6.2 at
IMDB, 3.9 at RT.)
Not sure what to do with those.
