[Q]: This is one of those books that I like the *idea* of, but not so much the execution. It's gotten to the point where if a book has the word "spooky" (or a variation) on the cover, I'm just going to assume it's not. The idea - offering ideas for six themed parties - would make for an excellent book if they were all actually Halloween-themed. Sadly, even the Halloween-specific party suggestions fall a little flat.
[A]: Negative

[Q]: This product requires a stereo player in which the balance is turned totally to the left. Most auto systems have that capability. However if you have Dolby or SurroundSound, it can be difficult (and maybe impossible) to play the cassette without hearing two recordings at the same time. Unfortunately neither the packaging nor the website will warn you of the problem. You therefore should think before buying. Once you have opened the packaging you may be unable to return the product.
[A]: Negative

[Q]: This movie overall was disappointing. I so liked the first two that I really wanted this one in 3D. This was by far the worst 3D movie I have purchased. The flying paratroopers is the only reason to see this in 3D. This movie as like a very bad opera - it just went on and on and on and on ... so that when it did end you were so thankful it finally got to the inevitable conclusion.

Negative
