[EX Q]: I have just spent 5 minutes trying to get this damn printer to print an envelope without mangling it. Wonderful.
[EX A]: Negative

[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]: Poor story, worse acting, appalling film making. This film sems to have been made to "showcase" the dubious talent of its maker and lead "actor". I've seen hammers with more expression and talent. Don't bother unless you're masochistic enough to sit through it. Less enjoyable than chewing tyres.
[EX A]:
Negative
