There is no doubt about it, Holly Braid Stitch IS a difficult stitch. I have the feeling, though, that the more you stitch, the better the result will be. So practice makes, if not perfect, at least better.
Also, once you get into the flow, the stitch is quite relaxing. Again, I guess that the more you use it, the better the flow will get and you end up having an enjoyable and relaxing time.
