I find Overwatch a weirdly cynical experience. Everything about it is calculated to an almost absurd degree to be The Team Based Shooter 2016-Forever, but for me it's entirely lacking the heart that made TF2 such a great game. Also the skill ceiling is about knee height.
There's no doubt that objectively it's a very good game. Blizzard have basically looked at every popular multiplayer game going, cribbed the best elements from each and carefully constructed a AAA-backed gundam with it. But it leaves me very cold.
