I have very mixed feelings about This new version of Galactus. Let me first say that the trilogy itself was awesome. Any story that incorporates Ayahuasca, Necronauts, Zero-Point Energy, the Multiverse and a planet-devouring entity is AWESOME. That should pretty much go without saying.
But with that being said, the 'Ultimate' version of Galactus just seems wrong.... For any newbs who don't know about Galactus, he's the "devourer of worlds". He's a God who destroys life who acts as a counterpart to the 'Creator God', sort of like the Yin to Creations' Yang or the Shiva to the Hindu Vishnu... Well.... in the old days (1970's to early 2000's), he looked like a Native American God of the Mayan/Aztec/Toltec/Olmec persuasion:
Now... the 'Ultimate' line of Marvel comics introduces a new universe in which the super heroes/villains are different than they are in the 'normal' Marvel Universe. (ie. the Fantastic Four are all teenagers, the silver surfer has wings, Beast has a lion's face etc...). The old version of Galactus will still continue to exist, but The new 'Ultimate' version of Galactus is not a Mayan/Aztec-looking God... He's a 'hive-mind' comprised of hundreds of thousands of city-sized insectoid robots.....wtf? I mean.... that's pretty cool.... I guess.....but......IT'S NOT GALACTUS!! To be fair, Marvel was aware of this fact, so they decided to call him "Gah Lak Tus". Nice try Marvel, but that's pretty lame....
