After finishing both routes, I'd say this is probably a perfect remake to me. The main problems with the Near Side routes were that action was unappealing and Ciel's route was too similar to Arcueid's. Welp, this fixes both of those problems. The actions become an absolute spectacle to watch, while still retaining all the heartfelt moments, while Ciel's route is basically completely changed and gives her character far more to work with.
Not to mention, the production on this is insane. While slightly less cinematic than Mahoyo, the amount of backgrounds and CGs is truly astounding.
My only complaint is really that it's only half the game, but I already know that Red Garden's version of the Maid routes will have me bursting into tears so I'm willing to wait.
