Honestly, the perfect crawl for me would be as follows:

It is a time of despair.
Luke Skywalker, sworn to
rekindle the light of the
Jedi Order, has vanished.

Emboldened by the Jedi’s
absence, agents of the
evil FIRST ORDER have
risen from the shadows
of an Imperial fortress to
conquer isolated worlds
beyond the reach of the
fragile New Republic.

With the Galactic Senate
in ongoing debate, a brave
RESISTANCE stands firm
against this oppression by
sending pilots in search of
the last Jedi, whose mastery
of the Force could restore
peace and justice to the
darkening stars. . . .

The crawl is the only place to directly explain why the creation of the Resistance was necessary. That’s why I opted to put that in there.
