I just saw the movie and its awesome, Way better than POC3 and S3
First of all galactus is NOT a cloud
Pay attention and let me elaborate
-The shadow looming over saturn IS galactus and it is genuine
-Silver surfer referred to galactus as a he many times through out the conversations he had
-A cloud cannot be referred to a he as it is neither male nor female
-A quote from the silver surfer while galactus attacks earth "He is here"
-And the final battle when they showed silver surfer flying up the clouds , please pay very close attention to what i have to say
Immediately after silver surfer says I will no longer serve you the camera shows what is infront of SS. If you pay attention and scan what is infront of SS. You will notice flames which actually make the shape of galactus helmet and he is infront of silver surfer growling.
They show this part a few times but note that you MUST pay attention as the scenes are very fast and no longer than 2-3 seconds
After that the camera would show the view of the clouds and the entire earth and you WILL see a glowing body resembling flames in the middle of the cloud. That glowing flame is what i mentioned earlier but this time they are showing part of galactus hips and right leg.
Before surfer blows up to kill galactus you will again see the flame head of galactus but for very short moments. Not many people actually noticed this
And right after Surfer knocks him out. The clouds are starting to dissipate and you will actually get to see galactus lower body which used to be the glowing body. Note that you will have to observe this quickly.
Now i am NOT lying about this and you problably think i am because many other reviewers stated they couldnt see galactus at all. I doubt they were carefully observing those pivotal scenes and if you goto IMDB.com Some one said the same thing as i said when surfer flies into the clouds. You can make out and see galactus entire helmet.
Before i end. The trailer showing the shadow of galactus head on saturn IS REAL as it resembles the galactus we know. Note though that in the movie the helm slight resembles ultimate galactus but as his shadow continue to move you will see the familiar "horns" on his head which resembles the helm we see in the comics
If you think i observe wrongly then i reconmend you actually pay attention to those scenes. Carefully observe them and you will see what i see.
I repeat galactus is NOT a cloud but he is INSIDE the cloud and instead of using machines to drain planets its the cloud which is his actual power
If you have any comments or questions please do post and ask though i will not reply as i will be gone in a few days
EDIT
lastly if galactus was a cloud alone he cannot be touched and thus is invincible.
And galactus CAN communicate as surfer stated he made a deal with galactus to find him other planets to feed on so Big g wont eat his planet
