Do successor Space Marine chapters need a distinct identity?

Why dislike the Crimson Fists, Novamarines and Angels of Vengeance?

The criticism is that these chapters are uninteresting; the reply argues that Angels of Vengeance has distinctive secrecy and motives that this overlooks.

Foxo names Crimson Fists, Novamarines and Angels of Vengeance as disliked chapters because she finds them boring. The developed argument focuses on the latter two as versions of their parent chapters with less interesting characterisation. Dragon disputes that reading of Angels of Vengeance, pointing to its deliberate obscurity and intense hostility toward aliens. He also identifies its refusal to cooperate with another commander's strategy as a flaw. The disagreement remains a judgment about fictional writing and identity.
