i think sudden fear is a very good example of the so called films noirs and also joan crawfords performace is very convincing as the frightned woman who tries to save her life as well as she can
Positive

I haven't been able to watch this much because the DVD won't play in my normal (otherwise functioning) DVD player. It will play on my computer's DVD player, but without sound. The DVD will play fine on my laptop, but that's not a screen that's very conducive to practicing in front of. The DVD does play on my friend's DVD player for some reason. Also, I bought volumes 1 and 2 and both are so short, it seems obvious that they could have put all of the lessons on one DVD. I guess they knew they could make more money by making us buy both.
Negative

I'm a 13 year old kid and I just finished reading this book for an English class I am taking. Although it was a very interesting and provkitive novel. I did not like it very much. I think it maybe that I'm still too young to throughly understand this piece of literature.
