I think 'childish' is a bit much. It sounds insulting. It's an amateur production, not a mainstream, or indie film, more like a fetish company production, but it seems like it's not even that, just one person with a camera. 'Amateurish' would be more appropriate, no offense intended. I think constructive criticism is good, but there are more polite ways to do it. If we support someone like uniformedwomenuniverse, and explain what works and what needs work, maybe some day he/she will have more ladies on set, have a bigger budget, have better acting and action scenes, etc..
