I am surprised, but not shocked. The cancellation cloud had been hanging over Brooklyn 9-9 at least starting last year. G-d, imagine if the series would've ended with last season's cliffhanger. :O
This saddens me. And I wanted to get at least one season post Amy/Jake marriage since their relationship was so organically developed in this show as oppose to most shows in which characters just end up together 'cause hormones.
Honestly, this show reminds me of The Simpsons golden years, which is high praise coming from me. And what I mean by that is that each episode has such a wonderful array of jokes and references which creatively grew out the episode's main or secondary plot. Many of which you would get after watching an ep for the second, third...
I am not willing to accept that there is no hope the show doesn't continue somewhere, but we shall see.
