The game has been amazing thus far, one of my favorites.
I'm enjoying most characters, especially hanzo. But I just can't get the hang of widowmaker (weird huh).
The balancing on PC is amazing. I'm surprised every character is playable and powerful without being op (especially after the widow and mecree nerf). I have heard that turrets on consoles are OP (due to worse aiming without a mouse and keyboard), but they already said they plan to fix it.
There is more than enough content. I've spent perhaps 10 hours on hanzo alone and that's 1 character. The has a ton of replayability and will only have more with the upcoming free dlc.
