This toy has peaces that fall off even while puting it together it kept falling apart the legs would not stay on and part of the tower would not stay together. I would not recomend this toy to anyone else or pay for it again myself.

Plenty of action and almost lives up to the others in the franchise. However, not to be missed or overlooked as one of the btter robot wars themed movies.

Ex Output:
Positive

Ex Input:
This series is a huge disappointment, in comparison with the fine nature programming I grew up with on public television. The scientific content here is low, and thus the educational value is poor. Instead, we are treated to disaster porn--stitched-together footage of calamaties and their aftermaths, plus alleged "human interest" stories as shameless as anything on the six o'clock news. Insultingly voyeuristic, if that's possible for Americans these days.

Ex Output:
Negative
