I'd like to preface this by saying I hated DMC 1-4, but DMC (2013) is some of the most fun I've had with a video game in quite some time.
I know it's just one opinion, but Garnett calling DMC "nothing special" is entirely reductive. To discount the amount of fun that a player has with a game and not even mention the creative level design or the great voice acting work that made those characters is is a terrible way to go about giving your thoughts on a game. I also have no idea how you call this game "ugly".
What I gather from his thoughts is that he didn't feel this game had the "spirit" of Devil May Cry and wrote it off regardless of the numerous things the game does very well, not to mention again, the amount of pure fun that the game is to play. The game goes and tries reignite the franchise as something new instead of trading on your nostalgia of prior games. If that's not for you, fine. But you don't need to go about trashing a good game because it's not the game you thought it should be.
