Spoilers are spilled, sez Stephen G. Greydanus. He rants, spoiler free, and I applaud.
I've gotten to the point where I tend to avoid all but the most cursory looks at advance reviews because too many people tell the good stuff.
In fact, I can't tell you how difficult it was to review Beasts of the Southern Wild so that people didn't know any more than I did going into the film. But I tried. I really tried hard.
