Totally disagree with you, Ian
, but that's OK. I love both shows, so perhaps I'm biased, but I honestly thought AGT was the almost perfect ending. But then, so was WYLB. I really don't feel a need to quantify which one (show or finale) was better. They were great, and I'm happy to leave it at that.
P.S. I also never noticed the reused battle scenes. To be honest, very few battle scenes stay in my mind longer than, oh, 27 seconds or so.
