[EX Q]: I didn't like some of the plot twist, of a former leader of the Autobots but other than that it was pretty good.
[EX A]: Positive

[EX Q]: The product seemed like a good idea but wish I had read all of the reviews before ordering. The product is not sturdy at all. It didn't come with the number of screws noted on the instructions so I had to go out and purchase more in order to finish putting it together. That was after I spent way to much time trying to decipher the instructions. Also, the clips that hold the bag to the frame are very tight and very difficult to put on and remove. I've torn every bag I've used. I hate wasting my money; but, I'll have to buy a better one.
[EX A]: Negative

[EX Q]: Any Dickens book can be summarized in two words: coal and suffering. I was forced to read this weepy piece of high-strung emotional swill in high school. Dickens lacks the punch and anger of Zola's sweeping "Germinal". For the best critique of Dickens, read "Against Nature" by Joris-Karl Huysmans. The high schools of America would be better off trashing their Dickens paperbacks and reading something with real value, like Lewis Carroll or the Marquis De Sade, both masterful storytellers of the absurdity of authority. Plus both Carroll and Sade are a lot funnier than the ever-serious monotony of Dickens. Do yourself a favor, steer clear of all those Dickens books in the bookstore and curl up with a nice volume of Sade.
