The explosion and what has happened afterwards is depicted as if a cruiseliner or a submarine is sinking; with all the shaking pipes, trembling ground etc. Of course I am not an expert but the mechanics behind an explosion in space should somehow be different.
Another such point is the holes caused by meteorites on the lifepod. I think it would be impossible to close one of them with bare hands, yet one of the characters was successful enough to close one temporarily and remove her hand afterwards. She should have lost the hand, but managed to survive with just scratches on her hand.
