Yes, in the original two films, one of the biggest mistakes they made was turning the legendary Galactus into a cloud. Yep, a cloud. We can see why they did it - mainly because they thought a bloke in a purple suit was stupid. But Galactus is eater of worlds! If you can't make that look terrifying, maybe you shouldn't be working on the film at all. Even a bloke in a purple suit would be better than a cloud, if we're honest. Galactus will have to show up in the film at some point, because really Dr Doom is a big fish in a small pond. If they get someone awesome to play the role, like Javier Bardem or Sean Bean, I think the character would totally work. I just refuse to believe that with all the technology we have nowadays that we can't make Galactus into a genuinely terrifying villain without him being a cloud. Come on guys... really.
