I feel Zyuohger's biggest failing are the villains, personally. They're your average set of boss, bruiser, smart guy, chick, like Gokaiger, Goseiger, Shinkenger, etc etc. None of them have really showed any particular quirks to really distinguish them, either.
While Genis being quite mellow over losses is a neat change of pace, as a character, he hasn't done anything to set himself apart from the likes of others.

I do think everything else in Zyuohger is really good, though. The rangers are a really work off each other well and balance out the team. I particularly liked their reactions to losing to The World, like GoseiWonder said. It was a breath of fresh air for Sentai~
