[EX Q]: Ugh! What a steaming pile of predictability this movie was. At least I didn't pay to see it and was able to read a software tech manual while "watching" this. The plot is thinner than the paper it was written on and the acting, well its typical Michael Bay which means you can see more believable productions at you local high school. It was easily an hour too long and the special effect have been used hundreds before. I think the saddest part was hearing Lenard Nimoy as Optimus Sentimental, I mean Sentinel. Gratuitous sci-fi pandering at it's lowest.
[EX A]: Negative

[EX Q]: Ordered two and tested them out: one had a bad pump but the return was easy.These airbeds are super cheap and great. Everyone who has slept on them says they are extremely comfortable. They hold the air well. I recommend them very highly
[EX A]: Positive

[EX Q]: This book [stinks]. I read this book only, because I seen the preview for the movie. It jumps around from one thing to the next. John Keel is a nut, "the phone rang and nobody was there!" "That could only mean the time traveling space aliens, cause no human would be capable of calling my house and hanging up." "The CIA/FBI are out to get me" Please!!! Go see a shrink.
[EX A]:
Negative
