The Last Jedi was the first Star Wars movie, excluding the anthology movies, to not have a major time jump. In between most movies at least a year up to 33 have taken effect. Meanwhile, The Last Jedi picks up about a few days after the events of The Force Awakens. The best thing about time jumps is that you can pick up with characters in totally different situations, but since this film did not have that luxury, it did not leave much breathing room.
There was a lot of going on during The Last Jedi. By the end, the slate was pretty much set clean for the new generation. It would be wise for the next film to pick up some time after the events of this film. There is a satisfaction on reading the opening crawl and finding out the set up for the film.
