Tough choice. Sorry to say it but the rushed finale is better than cliffhanger endings. In my experience. Cliffhanger endings have really triggered people a lot. I found cliffhanger endings to be annoying or a waste when a show got cancelled afterwards.
And I've seen that happen many times, especially when it was a show you'd think wouldn't get cancelled because of how successful it was. So sorry to say this but a rushed finale is better than a cliffhanger ending.
