End of Movie (Spoilers?)
At the end of the movie (after the meteor strike), were they trying to suggest that the melting of the polar ice cap had now filled the Martian "canals" and that there would be liquid water on the surface? And beyond that, that Mars would now be better capable of supporting life on the surface?
I'm not sure if that was the intent but, if so, it's kinda cool and predates the ending of Total Recall (Arnie version) where the Martian surface is similarly transformed into one more hospitable (although Arnie gave the people AIR!).
