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.

A: Negative
****
Q: Product reviews are very subjective. Based on the reviews of this boot I hoped for a great boot at a fair price. Instead I found the boot to be subpar in terms of comfort. They shoes were stiff and far too 'roomy'. My feet where floating inside them. I returned them immediately. I've had far more comfortable boots right out of the box.

A: Negative
****
Q: Learning arabic on your own is a challenge. I chose to supplement the Kitaab fi tacallum al-arabiya series with MSA Vocab Clinic to get up to speed a little faster. It gives good pronounciation help, and the word lists makes bus rides a lot more fun...

A:
Positive
