No, slow is a fair description of this. You need to start out in nearly the same orbit as the target and while you're both traveling around the Sun or Earth fairly quickly you approach the target much more slowly than you would in a Holman Transfer. Then when you're captured you'll be going around the target a number of times before other gravitational perturbances eject you again, giving a long time to do a burn to get into a stable orbit. So yes you have to change the momentum of the rocket but the burn could take place over the course of a week and won't have to be very large. Your burns to achieve an intersect giving you a ballistic capture would typically be much larger than with a Holman transfer but the slowness of the final approach means you're free to use an ion drive, solar sail, or other high efficiency and low thrust drive.
