Review of the previous season.

This is the final season of "Elementary." It's shorter than previous seasons at only 13 episodes - each of which is about 40 minutes long, the same as previous seasons.

The bogeyman of the season is Odin Reichenbach, multi-billionaire owner of a Google-alike company with its tentacles in everyone's private information. His take is that he's preventing the next 9/11 by pre-emptively assassinating people. Given his name, I assumed that the writer's end-game was to kill of Sherlock Holmes by the end of the series.

In the end, I think anyone who likes mysteries should be required to watch the first two seasons of this series: they're excellent. I didn't like season 3 much, 4 is okay, I thought the fifth season was brilliant at the time ... but feel less sure about it now, and 6 and 7 are kind of mediocre. The wrap-up is nice, and a pleasure to see (although it jumps forward in time multiple times over several years), but the season itself is only so-so.
