The review scores themselves are good. What itches me is the critical research failure in some tests. Like gamespot claiming the player has not enough time for the missions - which are not timed at all. Or polygon criticising the game not explaining it's mechanics - there are optional tutorials for that - and the User Interface cluttering the screen - each part of the UI can be activated/deactivated at leisure.
It's also not the first time. I can remember how many reviews claiming in their Splatoon reviews not knowing or unsure if there would be any content updates for the game, then seriously downgrading the game for lack of content and replayability.
