The Fantastic Four: First Steps is the first MCU entry in some time where prior knowledge of previous films/TV Shows is not entirely needed.
Admittedly, I was thrown off at the start when I found out the setting was Earth-828, which is not the main earth from the prior MCU films (that was…let me check…oh right, Earth-616). This is an interesting approach, since the Fantastic Four are, as far as I can tell, behind only Spider-Man and the X-Men when it comes to the most prominent of Marvel characters.
