I was watching the movie for the first time in a long while (since I was a child) and this time I noticed that after they landed, there were a couple of pyramids and a large (temple?) structure that made me curious as to what the writers of the screenplay and director had in mind with the ending.......a sequel perhaps? IDK, but it seems to require one.
Perhaps after someone else (R. Emmerich?) figures out that another great disaster movie could be made from WWC premise. I thought that 2012 kind of mirrored the theme of WWC, only with ocean liners. I think that he should have used spaceships instead!
