Let's start from the most ravaged chars.
Silver Surfer
In the comics he possess the Power Cosmic.This grants him a vast array of abilities, from superhuman physical attributes to energy and matter manipulation.And this doesn't depends from his contact with the board.Even if separated from it, no US Army soldier could have hold the Surfer.Surfer just went through the planet, causing CASUAL matter manipulation cause he irradiates cosmic energy all the times.But fact is, Surfer controls his energies and can control them, he just doesn't walk on the Marvel earth warping everything around himself.Also, Surfer isn't able to kill Galactus, so, the major bullshit finale, was just a massive USE of CGI to make the ticket worth of his value.
Also the effects of Surfers energy blasts, were not much good.It was too hard to find someone that could create a good energy blast to show in a movie?ILM, LucasArts, do I need to go on?They showed us an herald tortured by Russian soldiers, what is this?Surfer can duke it out with THOR FOR GOD'S SAKE.
Dr. Doom
My dead Victor, what happened to you.Surfer "frees" Doom from his metal statue form, and then Doom, who looks like Palpatine, track him down and blast him with an electrical bolt that looked more like a firecracker, get some good CGI you Tim Story.Then Doom gets turned back in his human form, but keeps his electrokinesis.And he show up to aid the FF4 and then keep the Surfer power source for his purposes.His final armor design was good, but the device on his wrist was very bad looking, Doom has access to the best hi-tech, that thing looked even worst than a morpher from the Power Rangers tv show.And when Doom gets the Power Cosmic, he blast here and there, use it to drag debris and water to his enemies, then a "Super Skrull" Johnny Storm wrecked him without much troubles, and Ben knocks him in the sea with a crane.
And this was the FULL DOOM Story was talking about?Never heard a director saying so much bullshit before his movie came out.
FULL DOOM MY ASS.His armor couldn't fly or do jackshit of what is can do in the comics, Doom wasn't even near to his Ultimate or 616 self.
