[EX Q]: This is a fabulous costume! My daughter loves it and has had it on every day since it arrived last week. She even slept in it a couple of nights. The other reviews are correct in saying that it needs some mending. We had to reinforce the velcro on the mask and the elastic on the bottom of the boots. After a little stitching it is fine. We also sewed on a small piece of material to the back of the face mask so that it wouldn't stretch any further and tear. This was a fabulous idea. Do it! I only deducted one star for this because the rest of it is great. The material is a durable shiny pink. My daughter is a size 4 and wears a size 9 shoe and the small fits perfectly. If she were a 5 or older I would get the medium. Totally worth the money.
[EX A]: Positive

[EX Q]: I received the message that the U. S. government is hiding knowledge about what is beyond Earth's atmosphere. But all governments hide information from the masses of their people. What intrigued me was when the Sentinel Prime character said to the Optimus Prime character that they used to be gods and now they were called machines. I can relate to that statement. I am a descendant of a people that were performing high sciences at one point in time and now we are beasts of burden. Try to talk to a typical African person about science and see what you get. At best they'll say, how does this help me pay my bills? At worse they'll look at you like you have 2 heads.
[EX A]: Positive

[EX Q]: The NBC coverage offered in these videos is fascinating to watch as it shows a tragic, unfolding event as it was covered live in 1963. NBC's coverage was in black and white, except for brief segments early on from WBAP-TV in Fort Worth. The only problem with the videos is the actual video quality...which is lousy. THIS VIDEO IS NOT AN OFFICIAL NBC RELEASE. THE MATERIAL DID NOT ORIGINATE DIRECTLY FROM THE NBC NEWS ARCHIVES. IT IS A BOOTLEG. NBC only released one such video of its JFK coverage, a capsulized version back in 1988 which contains almost none of the coverage seen in this collection. This material is of marginal quality at best...and looks like it ewas copied about eight times before being released in this version. If you're not concerned about this, then you will find it very interesting to watch.
[EX A]:
Negative
