Not too surprised. I felt the last season was crap. The show had promise in the beginning but really lost its focus and kind of went all over the place. Also losing Ashely and adding Kate were two fatal moves. Last of all, they really messed up with the character of John Druitt. Used him way too little, made him a tragic and sympathetic character and then had Magnus shit all over him.
Exactly how I feel as well. Not surprised at all that it was canned. It had promise for sure but the characters were just so lacking in some parts...but great in others. Ah well. Maybe that leaves some money/room for some nice new awesome SyFy show in the future?
