Really? It's the complete opposite for me. I thought the fighting was pretty lame. Can't exactly explain why, probably because it appeared like boring skirmish to me. Nothing really got to the point. And Aizen saying he's reached his limit while fighting Ichigo's father, when we've actually seen next to nothing of that fight (except for Isshin snapping Aizen through a few buildings which at most counts as foreplay in Bleach) was somehow rather incongruous, because Aizen being exhausted should be a big thing, which this episode totally failed to show us. He didn't even seem beat. And of course everyone always has time to for a nice talk and showing off with how awesome they are at analyzing and explaining, but that's nothing new.
