Question: 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!

Answer: Negative


Question: I am using this textbook in a class and it is a whopper. Wonderful pictures, easy to read, clear colors and understandable. I've been working in prisons for 5 years and this book makes a lot of sense. You ought to read their sections on women in prison and on probation. I loved the parts on geriatric prisoners (old cons) and the death penalty. And it is easy to read. More!

Answer: Positive


Question: Boy, this was a disappointing read. The characters were not well developed (hence challenging to keep track of), the plot was implausible yet predictable, and half way through I had to wrestle with whether or not to even finish the book. I did, although it was unrewarding to do so.I'd rate this lower if I could.FYI, if you're looking for an alternate selection in the same genre, I highly recommend Silent Joe by T. Jefferson Parker.

Answer:
Negative
