I don't know about ThinkRob, but the walking animations of the robots weren't fluid enough to jump the Uncanny Valley to me (also when falling from the tower). The eyepatch was really good (though there was a blip of the Valley when the character first showed up). The button also had something weird about it, but I couldn't put my finger on it. I've only seen it once, so it's not like I analyzed it for these things. FTR, I also had issues with some parts of Avatar (mainly with the mechasuits and flying things, IIRC) which I've been told isn't that bad, so maybe I'm just sensitive to such things.
