Then they talked about an expensive metal they wanted to grab called... wait for it... "obtanium".
That was about when my suspension of disbelief snapped, and I came out of the 3D-induced coma. That was also when I started to accurately predict every characters actions throughout the rest of the movie.
Final verdict: the special effects were top-notch, but everything else kinda... well, sucked. Entirely too long, all the characters were predictable, and the inner message was a little touchy-feely for my cynical mind - it's a good one, but also an unrealistic one.
Feel free to agree/disagree/whatever.
