I'm glad they got rid of Shia LaBeouf, I swear he screamed too much in the earlier films. The new guy seems like a rambling idiot though *SPOILER ALERT* Kind of glad the surfer dude died.
But anyway, the new characters seemed overly stereotypical. Giant American beer buster heavy gunner, Japanese swordsman, Australian gunslinger... At least they kept Bumblebee.
