This is great!

Here's a few interesting ones I've come across:

* The Wire (http://graphtv.kevinformatics.com/tt0306414)

Known for being a slow starting show, this is visible with the season trend lines.

* The Shield (http://graphtv.kevinformatics.com/tt0286486)

Season 4 is such a massive outlier.

* Seinfeld (http://graphtv.kevinformatics.com/tt0098904)

Held very steady until the last season.
