People rag on the Volume just as much as they rag on "too much CGI", the same they used to say "too much green screen" or "too many rubber suited aliens". It's all just storytelling tools, and you either suspend your disbelief or you don't based on the strength of the writing. If you can show me a seemingly endless corridor with giant hydraulic pistons that reconfigures every ten minutes, and that's actually a part of the story, that's pretty damn great in my book, no matter how it looks.

And just for the record, I thought this looked great too.
