Left Us Hanging?? (No Spoilers)

I just finished this series. According to IMDB it's 10 episodes but it turns out it's only 8 which means I've watched the last episode. It really leaves you hanging, with a horrible event occurring, among other things. According to what I've just read, the show hasn't been renewed or cancelled but even if it's been renewed, there will be a long wait to find out what happens.

It's actually a very good show IMO but I found it frustrating that they would stop it without an ending, amidst an intense story line and a horrible event.
