Here is a statement from the director:
"I totally regret it. I totally do. I’m not sure everybody does, but I definitely do. What I realized in retrospect — and after hearing all the reactions and feeling the kind of wrath of fans, critics, and people at the split — is that I realized it was frustrating,” he now says. “And I can understand that. In an episode of television, if you have a cliffhanger, you have to wait a week, or you could just binge it, and then you can see the next episodes. But making people wait a year, I think, came across as disingenuous, even though it wasn’t.”
Lawrence does state, though, that he was able to get more of the book material filmed by the split, allowing that four hours of film is better than two hours.

Learning from that bump in his past, Lawrence decided to not split the prequel "The Ballad of Songbirds and Snakes" into two or more film. The prequel is just one film and it runs for 2 hours and 36 minutes.
Here is a statement from Lawrence on not splitting the prequel:
“I would never let them split the book in two. It’s a long book, but we got so much s— for splitting Mockingjay into two — from fans, from critics, from everybody — that I was like, ‘No way. I’ll just make a longer movie.'”
Lawrence directed three of the four Hunger Games films, and is also the director of soon-to-be-release prequel, The Ballad of Songbirds & Snakes.
