[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!
[A]: Negative


[Q]: Easy to read yet scholarly. Great illustrations. Space in the margins for notes. Good chapter overviews and summaries. Nice T/F questions to prime the reader. Sources used appropriately. It is truly the ideal textbook.The format, layout, and writing style make this the text that other writers should follow.
[A]: Positive


[Q]: This film truly shows how filmmakers attempt to ride success. This movie is really bad. Even with some new blood (or should I say blonde) I couldn't hardly stand to finish the whole thing. But I did. What a waste.
