[Q]: The sizing of this costume was fairly accurate but it very cheaply made. After only a few wears, the mask and belt both broke. I wouldn't recommend this costume.
[A]: Negative

[Q]: Where to start I have had this for 10 years and it is still ticking that alone is a tesament to how well the thing works. Over that ten years It has traveled with me to over a third of the world. This is to include half a tour in Iraq. It has been dropped and has been trough airport security more times than most people. Because of this I have never had a reason to buy an Ipod. And to be honest for music I would rather use this. Only reason that I own anything like an Ipod is that its my Iphone. So I think that the Xtra is by far the one of the best mp3 player made.
[A]: Positive

[Q]: I mean, 2.5 hours? Really? The story line is so simple, this could easily have been a taut 90 mins and we all would have been a lot happier. I actually have not seen the first two in this series, so this only starts to make some limited sense after a long while. Anyone should be able to watch, though, and get it, thus the editing here needed more work. The absurdly plumped up lips of the girlfriend continuously transfixed me, way more than the silly transformer action fight sequences. Speaking of which, that is where all the fat is here. The fighting could have been seriously cut and no one would have complained except maybe the kids who made this comic book movie. Is anyone surprised to learn that the bad guys/good guys theme ends with the good guys in charge, yet again?
[A]:
Negative
