“THAT’S what you call a happy ending?…You just DESTROYED THE PLANET and you want me to care that John Cusack is stuck in a water-filled compartment? Check, please. But at the end they had these few survivors prancing out of the ark onto new land and we’re supposed to be happy about this?”
In my opinion, the biggest disaster was the movie itself.
The laughs at the expense of the movie are worth the price of admission, though.
