All Maia are 'servants' of their respective Valar.
Gandalf (in his Olorin incarnation) is the servant of Manwe, for example. Saruman was the servant of Aule (before he turned...) Radagast was a servant of Yvanna. And so on.
I don't get why some people here like the Sauron 'fight". It was confusing as anything. What was going on? This felt as such a forced tie in with LOTR in such a way it didn't make any sense.
Why did Galadriel turn into a Dark Witch like she did in LOTR (which was a moment of temptation where she overcame that dark side)? Now her dark side is used to fight Sauron? And why the heck did we need the whole LOTR anyway when Galadriel could defeat Sauron herself? Weird weird weird and contradictive.... seems like Jackson, Boyens and Walsh were clueless in forcing this stupid incomprehensible scene.
And another thing they did with The Hobbit: they made the Uruk Hai of LOTR completely useless. Saruman created the Uruk Hai to bypass orc weaknesses: physical strength and the inability to walk in daylight. But what do we see in The Hobbit: thousands of big, muscular orcs that walk and fight in daylight!! WFT????
They're not very well thought out movies. They're action packed (for Joe Blow), stuffed with references to the originals (for the J.J. Abrams Star Trek enthusiasts), and loaded with Tolkien lore (for the gullible nerds). This was a single movie stretched in to a trilogy, and all the filler that had to be injected was clumsily, often lazily shoehorned in for the sake of tricking the audience that there was any substance.
When Galadriel burst in to full on cartoon colors I laughed my ass off to keep the disappointment from overwhelming me.
