Marvel is assembling every heavy hitter left on the board for a giant cosmic brawl. With the Avengers, X-Men, Fantastic Four, and Wakandans sharing the screen against Robert Downey Jr.'s Victor von Doom, this is built from the ground up as a massive theatrical event.

Content-wise, expect standard PG-13 Marvel rules: lots of kinetic fighting, sci-fi weaponry, and high-stakes jeopardy, but no graphic blood or explicit content. The primary challenge for younger viewers isn't scariness so much as plot overload, as the movie assumes you already know who fifty different characters are.
