Gotta say, quite like it. What really gets me though is claims that Blizzard has abandoned its "dark and gritty" style.
Guys, have you ever played a Blizzard game? The only "dark and gritty" ones are Diablo and StarCraft. Warcraft's always had a bright colour palette and a high fantasy/swords n' sorcery aesthetic, and I'd like to remind you that Blizzard's games before that include Vikings traveling through time and space, a shotgun-wielding commando fighting space orcs, and a racing game where missiles are being shot between the racers. If anything, I appreciate Overwatch (and HotS) for the fact that while Blizzard can craft worlds and stories with serious intent (Diablo, StarCraft, Warcraft - palette notwithstanding), there's still room for enjoyable games that are simply about the gameplay (HotS, Hearthstone, Overwatch). That, and they've spread themselves out over multiple genres rather than focusing on one single genre.
