[EX Q]: My little boy is just getting interested in these blocks. They are too cute! He's learning to manipulate the block in his hands. The little things inside the blocks are adorable. Some spin, some twirl, some rock. A definate upgrade from the standard wooden blocks.
[EX A]: Positive

[EX Q]: I'm sure the information presented in this class is good, but the presentation set my teeth on edge. Sheri thinks she is funny when she talks in a screeching voice and makes fun of new mother's foibles in her "funny stories". I cringed every time I heard her squeal as a pretended mother with a problem. If you can get past her, then I guess the DVD can give you the information and techniques you need for Lamaze. But unfortuanately Sheri spends more time talking or shrieking while trying to be amusing than just giving the information you would like to hear.
[EX A]: Negative

[EX Q]: This is by far the worst movie in black cinema. Take everything you liked about "Friday", "Booty Call" and "CB4", leave them out of this movie and this is what you get. 90 minutes of [stuff]. It is low budget beyond low budget, and you get a headache from listing to fake, incoherent characters who look like they were picked off the street of some ghetto. And those who like to see booty-there is basically none, just one scene which lasts about 15 seconds and features a silent, unattractive "dancer".. If you are a fan of these movies, rent it first, you'll see. If you buy it, you will find a movie devoid of beautifull black women and good looking guys, but which is filled with stupid humor and a story which will put you to sleep.
[EX A]:
