It feels shitty to criticize this at all given that it is easily the best free DLC ever, it easily offers more content than the majority of paid single player DLC.

But Valhalla isn't great. It focuses on combat (which was certainly the best part of the disappointing Ragnarok), it has great callbacks to the original trilogy, and it offers touching story beats that feel like a definitive conclusion to this chapter of Kratos. But more than anything else, it's boring and fails as a rogue-lite. I can't fathom why anyone would continue to play this after finishing its story, and even then completing the story itself is just frustrating with how often your success is rewarded by having to start all the way over because Kratos "needs to think."
