Second viewing
Just watched it again there for the first time since it came out.
Yeah I have the same opinion as I did then. Practically no story at all, just a concept and a situation that was basically repeated three times before an abrupt end.
I was really enjoying it when Sandra and Cloony were a team but then it went all weird and as I say, it just started repeating itself and then all of a sudden it was finished.
The whole film could have done with an extra half an hour maybe at the start to flesh things out or even just do something different instead of wait for the debris to come again.
Can't fault the visuals though and there were points when Sandra was trying to grab on to the various space stations which were really tense but as a film it could have used some bookends.
