I liked this one - it's a story where they are showing how they rebuild the resistance after it was nearly decimated in The Last Jedi. But more than that, it's giving some of the other characters that aren't the main ones their stories since there just won't be time in the movie. Particularly Leia since her life is winding down, and also Poe, showing how he grows to realize what it means to be in command. We see some old friends from various places like the movies and other novels; and it's not something that directly takes us into The Rise of Skywalker, but a bridge between movies 8 and 9.
