I like kimuras and I like the Brennan DVD. I think the audio, video, angles etc are good. He starts from guard, and then demonstrates some responses based on opponent's response. The first two, when the opponent straightens the arm or grabs on his leg, I think are both pretty good breakdowns and "high percentage". Both helped me out in areas where I got stuck. He works into armbars if the opponent rolls away and I think by spinning under him as well. He also go through a sequence from cross sides and shows some alternatives.
Though he doesn't say it, he shows the armbar that Laiman caught him with in a match, off a Kimura that Brennnan was attempting. He then shows a response to that as well, so I thought that was pretty cool for him to break that sequence down. There are a couple of foot locks thrown in at the end.
I think does a pretty good job of showing some solid transitions and response based of kimura attempts, and I'd recommend it.
