Agreed. I dislike unnecessary invented scenes as much as anyone, and dreaded seeing the cliffhanger, but now that it's past I am sanguine about it. Really, renaming Cleos Frey to Alton Lannister (as if one line explaining how a "Frey" could be on the Lannisters' side would be so impossible to fit in) annoys me more; I think viewers, who have already seen that the Frey family is gigantic, can be trusted a little more than they were in that particular case.
