Great Sequel, but why adding something not important too much?

Rating: 8/10 (2 February 2020)

First, I like their look when they're adult.
Second, love how the story going.
Third, it also got me in jumpscares.
Fourth, I love the ending.
But what's wrong?. The movie is TOO LONG, I know adding some flashbacks are good. But, don't add it too much. You're destroying the movie flow. But still, they got great ending and finally they end it at all, right?.
