Personally, I never cared for the show and am not surprised that it may get canceled. There were serious issues with the accuracy of the some the episodes going back to the original 2 hour premier / pilot. I wasn't too impressed with the CGI either - it was decent but in the end it seemed more like a cartoon rather then a historical recreation of 'the best dog fights' (btw I don't consider bombing ships 'dog fighting').
