I watched this last night. Wasn't terrible, but left a lot to be desired.
I felt it was rather slow moving and even though understand why there was no true explication for what happened on Earth, I wish we'd gotten one.
I felt confused too as to whether there were actually any survivors on Earth short of Augustine; two of the crew headed back down to bury their comrade and to seek out ones family.
Would they even be there? Was Earth ultimately doomed? Was there any real need of an imaginary child?
