Season 4 hasnt been great so far, but I thought the same of season 3 and enjoyed the later episodes.

They'll probally go back up if they add Jerome again.

When I looked at the show's American viewers per episode, it seems like its really decreasing dramatically. For example, the most recently released (as of writing) episode only got 2.75 million American viewers. A very low number, especially compared to the stunning 8 million American viewers for the pilot episode. That really can't be a good sign for the series. How likely will Fox eventually cancel the series? I wonder why Gotham's viewers are really going down per episode?

There is no way to know for sure how many people are watching. That data is taken from a very small portion of the American people. I can't imagine how anyone can base any decisions on such incomplete information.
