I could be wrong, but I dont think its supposed to be the last one. Of course, that all depends on ratings. Dan Harmon is gone and they moved the Показать to Friday, so it looks pretty bleak. Still, dont give up hope yet. This Показать has a very loyal fanbase.
the thing is theyre really close to 100 episodes and the cast сказал(-а) that they would probably be granted at least the 100th episode, but no one could be sure. though i, along with 1073 other Фаны of community, seriously hope that the Показать will last for a longer time.. Ты never really know with network television.
