I beat it a few weeks ago: The DLC is pointless, its weapons that randomly drop except you can use them slightly earlier. The weapons are also not that great. It has a bit of backtracking, but no worse than other metroidvanias I have played. I didn't get the "true" ending which just involves grinding/exploring more to level up. Think I was slightly off on that, but its just a different cutscene. No new fight.

I enjoyed it, though I do concede I played it coop.
