Overall, they did a good job with the characters, but you’re right in that Reed isn’t exactly cinematic.

They didn’t really show his stretching powers, so instead you just had a lot of him lecturing which, yeah, that’s Reed, but not good for a movie Reed. 😉

Also, everyone had a role to play except Ben. Reed was figuring out how to stop Galactus, Sue was a world leader and tight with Mole Man for the big rescue at the end + wrangling Franklin, Johnny did the alien translation work because he thought Surfer was super hot… and… Ben was there too? I guess?

They had snippets of him at the school for Jewish kids and kind of implied he was getting with the teacher… but nothing really.
