Days Gone - Sony Bend's biker open world zombie game

Why would reviewers bother to fully play an entire game that was so fundamentally broken upon release?

I own Days Gone on PC as a morbidly curious person that bought it at launch on PS4 and couldn’t get into it because, well, it was a fucking mess.

I dropped it and never thought about it again until I got it on a good deal for steam. Now, I don’t even want to bother. Though I am morbidly curious as to how bad it could be.
