What do I need to know about the Fantastic Four to enjoy the movie?

I’m not sure you understand how big the WTC actually was.

In comparison to, say, large chunks of NYC disappearing in a huge struggle between heroes and villains every week? On that hypothetical scale, even 9/11 barely rates.

Exactly. Sure it’s big to us but when an entire city has gotten wiped out in their universe 2 buildings is nothing.
