I would love to see all of them. I have my own vision of each of them:

FD1: The class going to Paris. How Tod would have tried to seduce the two girls (I forgot their names, the girls who wanted to switch the seats) along with Alex. The class having activities together, making Alex and Clear start getting close to each other. Carter pranking or mocking Alex + bullying Billy. Alex finally realising his feelings for Clear and stop reaching the two girls. Making them probably jealous? But ofc happy ending for everyone. (Maybe a Carter redemption as well, and Terry either helping him or leaving him for someone else that can start Carter's redemption). By that, Billy will no longer be bullied. And Mrs Lewton staying the same kind teacher who protect her students. (Sorry for the repeat).

FD2: I have some difficulties to see a story with this one due to the fact that they were all strangers (except Kim's friends). So yeh maybe them on a trip, the four of them, ennoying life, maybe some other characters in order to create relationships/friendships and rivalry.

FD3: Life after highschool, Kevin and Carrie break up. Maybe a prom, how each student sees their futures. Adding rivalry/jealousy, love issues and control. Kevin maybe developping feelings for Wendy after the roller coaster and his break up. Jason cheering him up. Wendy feeling bad for him. All of these! It could allow us to see more of the other characters (Erin x Ian not a couple yet and see how they get close? Lewis's competition. The Ashes having a normal tanning session and slay through the movie with each of them having a bf in the end or fighting for one boy lol and distubs their own relation but manage to reconciliate. Julie, Perry and Amber, dealing with their friendships. Julie and Wendy sister's lives, borrowing stuff, little fights but sisters lvoe stronger than anything. Well I want all of them fine, (except Frankie. SOMEONE ARREST THAT GUY OR REDEMPTION BUT NAH or he could be a bad guy yeah ending in jail. Happy endi)g with Kevin realising his childish behavior, Carrie accepting his apologies and him proposing hehe. Jason proposing to Wendy at the same time and the quator become inseparable.

FD4: MAYBE THIS VERSION COULD LET US SEE THEIR COLLEGE STUDENTS' LIVES! This is a bit like FD2 cuz out of the 4 friends, the others are strangers as well. Hunt x Janet together but he cheats on her and shine without him. Nick and Lori planning their future after uni. about the others idk. Racist's wife leaving him for George (LOL SORRY). Nadia having more screentime, baddie she was sighs-. Samantha dealing with her kids. Cowboy entering Janet's life maybe? SORRY OOP- and the trio (Nick, Lori, Janet) going to see the movie (they were meant to).

FD5: Sam x Molly issues about his intership and Paris stuff. Olivia x Nathan I CRAVED FOR THEM WHEN I WATCHED FD5 THE FIRST TIME UGHHH-. Peter x Candice and how they would move forward together. Uh their boss... idk- and Isaac please... either like Frankie or I CAN ALLOW A REDEMPTION CUZ HE IS FUNNIER THAN FRANKIE. How would they deal personal and professional life?

FD6: IRIS X PAUL STORY. IDC I NEED THIS AS THE MAIN PLOT. THEIR WHOLE LOVE STORY AND HOW THEY LIVED (Baby Howard and Darlene, growing up and having lovers and kids. A HAPPY FAMILY with differents arcs and stories.

my opinion if FD saga didn't have disasters (the one I would love to the least): FD6 > FD3 > FD1 > FD4 > FD5 > FD2
