This episode should have gotten many more viewers just for the presence of Rodney! And it would have. I blame all the angry SGU fans for boycotting this episode just to make SGA look bad and to remove all chances of it ever coming back. I also blame Syfy for not wanting this episode to succeed so they do not have to worry about bringing back SGA. Once again they shafted their loyal viewers because they simply do not care!
Think about this: All 800,000 people who watched the episode on Monday were SGA fans. If the 800,00 SGU fans had not refused to watch it, the McKay episode would have had 1.7 million viewers, which is exactly the ratings SGA was getting mid season 5.
