Writing a decent story means, at times, that you may be walking a fine line between a well-paced story and one that drags. Well-paced doesn't necessarily mean fast-paced. Have you ever read a book or watched a movie/TV show where you found it difficult to stop?
That's good pacing. And the best ones blends fast and slow pacing very well. It would do you well to study how it was done.
A few weeks ago, I decided to watch all eleven Star Wars movies back-to-back, in chronological order by the events in the movies, not the release dates. I started with the three prequels, then Solo and Rogue One, and of course the original trilogy and finished off with the sequel trilogy Now, before you ask, I didn't watch them straight through without any sleep. Lord no! But it was interesting how quickly I moved through the first movies--including the prequels--and by the time I got to the final sequel movies, I found it difficult to watch for too long. In fact, it took longer to watch the final trilogy than the others.
Then I discovered why. Pacing.
Even Rogue One and Solo didn't suffer from a pacing problem.
If you view the sequel trilogy, there is a problem with the characters having to explain EVERYTHING. True, there was some explanation in Phantom with the whole midichlorian thing when it came to the Jedi and Sith, but it was done quickly, in passing, and then we moved along--well, some were upset by it and still are to this day.
Remember. Not everything needs to be explained. And mindless banter just for the sake of banter only drags the story along. Not that dialogue needs to be eliminated. If you want a lesson on dialogue, read anything by J. D. Salinger. Especially his other stories.
Watch one of your favorite movies or read one of your favorite books. I can almost guarantee you that the pace of the story doesn't suffer. Events don't always have to be explained in great detail. Even Tolkien didn't explain a lot of the events in Lord of the Rings. Neither does Rowling and George R. R. Martin, when it comes to their worlds.
Please leave something for the imagination.
