Personally, I think that's stupid. It's just one way to go, but there's no real reason Galactus can't be the bad guy in the first film and Mole Man be the bad guy in the second film. In both cases, if you're battling someone who can destroy the world who cares if it's Galactus, Mole Man, Molecule Man, or Annihilus? If it's just a good movie, there's no need to use the villains to "build" on each film, especially when the next one is in no way guaranteed. (just ask Green Lantern)
Besides, Galactus is mostly "big" in physical presence - he doesn't exactly need multiple films to build his character or anything resembling a character arc. The FF's main villain is Dr Doom anyway because aside from power, there are personal stakes involved. (and we've all heard how he needs to be "built up to" as well)
