I was entertained throughout. The visuals were mostly good (except the "moon rises" and the laughably bad flooding scene) but it was the plot that gripped me. I was torn between pondering how many better films/books were mercilessly plagerised and wondering how many morons were in the script writing gaggle/team/committee.
Truly a cinematic spectacle to behold.
I think my favourite moment was when the chopper with the 2 nerdy NASA guys crashed and everyone obviously died and the leads didn't even react, give any hint that they gave a single toss or even mention it. Such feels, much brilliance.
