Haven't picked this up as i own all those early Iron Fist comics as singles and have bought the Essential Iron Fist. These are pretty much all of the Iron Fist solo available (except for some Marvel Two-in-One's) prior to Fist joining up With Luke Cage, Powerman. It is terrific 70's Kung Fu(ey) goodness. Some parts better than others as different writer's and artist's play round robin bulding the beginnings but the character truly comes into his own under Claremont and Byrne's contributions. Lot's of what may seem as random or strange in the context of the stories eventually become bigger or stronger story point's later on. I think it captures perfectly the time and essence of the bronze age and the 70's.

Agree that early '70's Iron Fist is a great series; the origin story reminded me somewhat of the origin of Caine in the great '70's TV series Kung Fu.  I have the first IF MMW & possibly the second one; IIRC, these contain the issues that were in the Epic Collection.
