They are all so young. I may be rusty on the series, but isn't Johnny like Sue's son in the series? Or are they siblings. Reed and Sue just seemed more mature in appearance in the comics. I mean Jessica Alba is great and all, but couldn't they cast her as Doom's wife or something?
I don't know what the "current continuity" is, but originally (in 1961) Reed and Ben were both college grads, as well as being veterans of WWII... so when the series started they were supposed to be in their early-to-mid 40s, I would say.
