There's a lot of missed potential unfortunately. Should have been set up to receive regular content releases/DLCs for probably 3-ish years or more post release.
That's pretty much the only bad thing. The game as is, is incredibly good. Amazing gameplay and gameplay loop; great line up of characters; solid build potential; fantastic bosses; etc.
I have almost 500 hours, and I certainly don't play as often as when it first came out. Still, played a round yesterday, and it was genuinely one of the most exciting gaming experiences I've had, and, remarkably, the same can be said for most runs I've played.
For the right audience, this game kind of hits like no other.
