This film operates best in your are already predisposed to like "ozploitation". If so you'll love it. I know I had a heck of a time, it's funny, also it does rely mostly on the interviewees talking, it uses lots of footage, images, and cool animations to really present the film as exciting, if not overstimulating. But hell, it's exploitation, and some of the best.
The set up too is interesting, as it goes sort of in chronological order, but mostly by order of sub-genre, starting out with the sub-genre that began relatively the earliest and who's popularity ran out relatively the earlier as well, then moving on as such. They also don't give general information but rather use certain films as case studies to illustrate what was going on at the time, as well as get into the production and reception of the films themselves.
The only problem I found is, although I am a fan of his, Quentin Tarantino becomes a little annoying by the end of the film. That being said he knows his shit, and praises the hell out of the films, so it's no wonder he's in it so much.
If you're interested in exploitation and genre cinema, you'll find it hard to walk out of the theatre and not want to see every film featured.
