First off -- All 8 live-action Star Wars films (I don't count the animated one) are in the top 100 adjusted domestic box office of all time.
That's beyond successful.
Secondly, despite the franchise's success, note the significant drop off between first installments in a trilogy and its follow up film.
The Phantom Menace to Attack of the Clones saw a
$329,013,400 adjusted revenue difference.
A 41% decline
Star Wars to Empire Strikes Back saw a
$713,854,900 adjusted revenue difference.
A 45% decline.
When looked at through a narrow lens, people will compare The Force Awakens totals to The Last Jedi totals, and claim that it is not living up to 'expectations'.
The Last Jedi will make Disney plenty of money in the long run. Currently, it is not keeping pace with The Force Awakens, nor do I expect it to ever catch up based on past trends.
