I wish I'd read that post instead of the critics' favorable reviews, also written by people who know nothing about SF, evidently. The first part of the movie is fairly good, establishing the reason why mankind needs to find a new place to live. Earth's resources are pretty much depleted; the whole planet is one giant dust bowl. One scene shows a family eating a meal, and all they have on their plates is corn. So far so good.

But once the hero leaves his farm to pilot a new spaceship in search of another habitable planet, the movie veers off into the ridiculous. One preposterous sequence follows another, and the plot loses all connection to logic. A movie like this can only have a fairy-tale ending, and that's what Interstellar has. Take Austin's advice -- don't go.

But yes, Rosetta is far more exciting! Comet-riding stories have been around since the 1950s; the first one I read made me think what a nice fantasy! Wish-fulfillment SF, and rather clever. I couldn't take it as prophetic for a number of reasons, such as the surface instability of comets. Of course, a lot more is known about comets now than when those early stories were written, but I still tended to think landing on one wasn't possible. But now they've gone and done it! I guess Arthur C. Clarke was right: If man can think of it, man can do it. We'll have to see whether the big questions will be answered (Did comets seed the earth with life?), but, oh my, what a giant step!
