I thought this movie was awful. The CGI and the fact that Halle Berry still looks like she is 30 as the only entertaining stuff. The story is absurd and despite having a huge budget I still found it boring. It took me 3 sittings to finally get all the way through this. :)
With you you can't lie halfway through the film I was already bored, at first it seemed interesting to me because of the theory of the moon but the only thing they did was half show the structure and not the facilities. After that I went to see another movie.
I think you made the correct choice by watching something else.
