In the hot summer months, everyone's looking for a way to cool down. This summer, movie audiences decided one of the best places to beat the heat was in the barren, 47-degrees-below-zero but otherwise splendid climate of Antarctica. The runaway (or waddle-away, as the case may be) limited release success of the summer, "March of the Penguins," melted the critics' hearts as well, notching a big 94 percent on the Tomatometer.

However, the summer's biggest critical (if not commercial) limited release was "Murderball," a tough-as-nails documentary about quadriplegic athletes that scored a 97 percent on the Tomatometer. Other smaller films also reaped big critical praise. "Saraband," the final film by Ingmar Bergman, arguably the world's greatest living director, garnered a 93 percent on the Tomatometer. Werner Herzog's "Grizzly Man," one of the strangest nature documentaries ever, netted 92 percent. Rounding out the top five is "My Summer of Love," a poignant tale of first love, at 90 percent.
