Well, for me there were some moments that could've been done in live-action, but would lean towards CGI (if they were trying for some shot-for-shot type of stuff). For example, certain moments where it's the multiple copies of the same character models walking or whatever. I honestly feel that since the Internet is the Internet, there would be some kind of complaint about that. Same with some of the shots that would require some green screen usage rather than practical sets given that's how Hollywood does things now (even with all the money at their disposal). But, they at least built a set and have to account for actual human dancers (and animals) and the room they need for their moves.
Like I said, I think it's just fine. And sure they could've punched the energy up.
