[EX Q]: Just "assembled" the bat cave for my 5 year old. Pathetic construction and workmanship -- half of the gimmics don't work. Another pile of injection-molded plastic parts and stickers that I get to assemble -- what is this thing -- $4 of raw materials + $2 of shipping + $10 of marketing? Garbage. Shame on you Mattel, the only thing worse is the batman figures with the batarangs that take 30 minutes and a blowtorch to get out of the packaging. This batcave will collapse and die within hours of play, I'm sure of it. GARBAGE!
[EX A]: Negative

[EX Q]: This book preaches a very right wing kind of economics. If you can imagine one of Rush Limbaugh's readers or helpers writing a primer on economics, then this is it. Keep government small etc. The author most likely was an Austrian school follower. As it is avaiable free on Limewire, maybe get a free copy on the Net or browse it in your local library. No need to buy unless you want to flesh out (sic) the ideas of Mr Limbaugh et al. The book relentlessly hammers home the ideas that government should be amall, self interest drives the economy forward and that state intervention is bad.
[EX A]: Negative

[EX Q]: I have previously purchased a Ross Berstein book ("Gopher Hockey by the Hockey Gopher") and found that to be an entertaining read. Not so with this offeringAll Berstein seems to have done is find some of Herb's friends, turned on his tape recorder and then transcibe their comments, verbatim. The print is too small, the words and thoughts are redundant and the small paperback has the look and feel of a self-published work, which it is.The range of interviewees is tiny compared with the breadth of Brooks' life and all the interviews sound the same. There were a few pictures of young Herbie the player. Those are fairly interesting, but I found myself a little disappointed with this offering.
[EX A]:
