I am certainly familiar with the idea of archetyeps and its use in psychotherapy, specifically in Jungian analysis since its a Jungian concept.

I find the idea fascinating, but to me the fascination is mostly about the idea in theory. I've never used archetypes to work on myself and I've never used them in my practice, so I can't speak of their practical effectiveness.

My apologies to all the Jung lovers, but for me the entire Jungian psychology is fascinating only as a spiritual theory but it doesn't have much of a practical value. Besides, having studied many esoteric theories and schools of thought on my own I could see that Jungian analysis is basically a stew where all those ancient teachings were used as ingredients, and I prefer to go for the pure, original substance. As anything esoteric, Jungian concepts give me a bigger vision and, in that sense, they help me maintain a sense of my life purpose. Beyond that they are useless to me, they don't help to deal with my everyday earthly struggles.

Again, this is just my own experience. There might be people who find archetypes helpful on a practical level. We are all different and our needs are different..
