With the last week of Box office, STID has helped the franchise cross $2 billion in adjusted dollars domestically. Overall it's close to the $3billion mark.

In fact, the only Trek movie UNDER $100 million adjusted (and under it by quite a wide margin) is Nemesis.
TFF also has one of the best scenes in the entire franchise with McCoy, Spock and Kirk facing their pain as Sybok says especially McCoy ending the life of his dad.
