First Steps is bringing a new generation of stars into the longtime franchise, but is it also suitable for a new era of viewers? The Marvel film, which premiered in theaters on July 25, is the third adaptation of the Fantastic Four comic.

The Fantastic Four: First Steps follows Marvel's First Family during a pivotal time in their lives: The pregnancy and birth of Reed and Sue's baby son, Franklin. That also coincided with the most significant challenge the Four had yet faced: Their planet served up as a snack for the intimidating Galactus.
