The main message I got from this film, is that there is a lot of debris in orbit that really needs to be considered soon.

Honestly that was the main message. The rest of it was mainly a well done treat for the eyes.

Yes there was a long time between camera switches which was a visually nice effect. (each take lasted so there was time for the immersion experience into space, which gave the film some...some. atmosphere?)

For the actual film content, I was left feeling that it was a film, which included a lot of real-world considerations. No, it wasn't "real", it just included a lot of the issues that they'd experience. I wasn't left feeling "this is space", it was "this is a space film, with a few doses of realism".
