Data Mining Just for Fun
A friend of mine and I happened to disagree on the overall
quality of Sci-Fi movies. I thought they were worse than average, he thought the opposite.
Since quite a number of hours of watching Sci-Fi was at stake, I decided to gather some
user rating data from IMDB. To my satisfaction, Sci-Fi was
the second worst category (horror was #1), with an
weighted average vote of 5.26 vs. 6.22 (out of 10) for non-Sci-Fi movies. Which isn't to say
that all Sci-Fi movies are bad. As can be seen from the graph,
there are a few excellent Sci-Fi movies, but there are also a lot of bad ones.
Here is a full list of ratings and vote distributions
for other categories.
