Apparently, this brilliant product sailed over the heads of some other reviewers.
First, the heavy accents of the Romanian speakers are deliberate, as is the lack of written material.
They are forcing you to learn language like children do, via call-and-response. They are teaching you to pronounce words properly, and keeping you from lapsing into Americanized speech habits. If you are in the frame of mind where you think you know enough to criticize the accents of people speaking a language you obviously know almost nothing about, I don't see how you expect to learn anything. Find your beginner's mind.
Second, the bizarre dialogs are obviously supposed to be funny... and very cleverly played in my book.
For instance, in Lesson 9, the guy asks a married woman out over and over again, a dozen different ways, too dumb to take no for an answer, until she finally yells at him for obviously not understanding Romanian. (My Romanian friend laughed and said the woman would have hit him over the head with something long before that). There is also a dialog where a couple orders a wine and beer each, at the same time... huh?
I think what they are doing is trying to make learning more fun. Even better, by not telegraphing the jokes, they are allowing you to discover for yourself that you are not just mindlessly repeating phrases, but you actually understand what is going on in the conversation - enough to know that something is amiss and maybe even have a laugh.
This may also be an introduction to a typical Romanian sense of humor, though I am not sure. Since the weird dialogues are all dating-type situations with the guy often offensive, dumb, or both, it appears they are poking fun at the intended customers for this program - traveling businessmen. While it's true that there might have been room for a broader vocabulary otherwise, a vocab core-dump is obviously not the purpose of this course.
Finally, I took French for years in HS and college and couldn't speak a word when I went to France directly afterward. I tried German in college and quit. I've tried to pick up other languages using other self-programs, including Rosetta Stone, and always quit in frustration. The problem is that most instruction gives you language pieces and analysis, like they are trying to teach you physics or math.
Instead, the Pimsleur method is carefully designed to teach you real speaking skills. It seems based more on a model of learning to play a musical instrument. I was addicted after just a few minutes. In less than two weeks, I've learned more about actually speaking a new language than from all the other classes and materials I've ever tried in my life, combined. I'm looking forward to lessons 11-29.
