I like how he has ZERO control whatsoever, including trying to kill everyone and everything around him early in the movie, but can take orders, and only goes after the bad guys at the end of the flick. The Avengers is awesome
Eh, they did a bad job of communicating it, but it's quite normal for the character. Banner isn't ALWAYS in control, it depends on what's going on around him. But he CAN be in control. The movie did both.
And do you forget the ROD? The entire inverted shot of the reflection in the Rod was a visual clue to tell you that the rod was taking control of everyone in the room (while also a nod to LOTR), including Banner. Hulk just needs to be set off in the wrong way and Banner is out, Hulk has complete control.
Many have speculated it's the Mind Control Infinity Gem, which would make sense, but that's nerd info only clearly that's why they needed to communicate it better. But in terms of story the shift in Hulk control is canon.
