Does the TV show Roar have an ending?

Roar was a FOX show starring Heath Ledger. I am watching it and I know it was cancelled but I want to know if it ends on a cliffhanger or if it concludes. Shows like Jericho were cancelled and yet they were able to conclude but shows like Firefly just randomly end. Does Roar suffer the same fate? Or is it a nice complete short series?
