We don't know about his perfect Susanoo, yes at that time indeed it haven't been shown but on the other hand since he had EMS it would make sense for him to have it, and besides that whole "reaching the other side" was done with Kurama's power as well and it was at that moment when Madara believed that he would defeat Hashirama. That being said, in this fight, indeed he hadn't reached it as he didn't have what it takes.Madara hadn't "reached the other side" until the VoTE fight, so he shouldn't have had PS yet.
The artwork and animation were all over the place.
The fight scenes were done poorly with pitiful pacing.
As for the other I don't agree but eveyone can have their opinion.
