First Steps' is as action-packed as any Marvel film, though a little less gory than its previous entries. Here's everything parents should know before taking their kids to see 'The Fantastic Four: First Steps.

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.

Marvel's First Family is finally part of the MCU with "The Fantastic Four: First Steps," and they have a truly storied history. But that might make you worry that you have a lot of homework to do before seeing the film.
