frandroid | Elementary season 5 end (some kinda spoilers)

WTF was that? This was the most unsatisfying story arc of the whole series. Suddenly Sherlock has a secret friend who's not introduced to us and never explained, until the end, with the most lazy excuse of all time. The whole plot with SBK ends up being convoluted and the resolution unsatisfying. This ain't no criminal mastermind.

I was enjoying this season and they just did this lazy writing. Just a little more set up would have been great, for starters.

This writer is more generous than me (full spoiler review), and sees some good in how this was put together. But humpppf.
