Woah woah woah, I think you guys are getting a bit mixed up here. The second movie was the terrible one (racist caricatures, giant ship gun that just appeared out of nowhere, ****ING ROBOT HEAVEN). The third one at least tried to make some sense, and did a better job at conveying the oncoming robot apocalypse than the second.
And, I don't know about you guys, but I like Shia. Liked him since Holes actually. He's awesome.
