Yes, but with enough improvements to make it worth you time. Or if you just prefer the Medieval Fantasy theme.
At its dead heart, Zombicide Black Plague (ZBP from now on) is pretty much your baseline Zombicide. You wander around the map looking for better weapons and gear, kill a bunch of zombies, and achieve the missions goals. Or die trying. Still a fast moving, fun game for 1-6 players.
The Zombvivors are gone, which I feel is for the best, I was never a fan of the way they were implemented. It is much easier to heal your characters now, so player eliminations will not be as frequent. The Necromancer is a nice addition as a bad guy, but I kinda wanted it as a "boss monster" rather than a special wandering monster. Still adds nice flavor, they just show up too often.
There is a tidal wave of expansions coming for this game, we got in on the Kickstarter, so an nearly unusable number of new heroes and cards will be here soon as well as the first expansion which adds werewolves. That is the big question for us: How many fantasy monsters are they going to add? How fast will it make the game an overencumbered mess? Maybe they will keep things separated: Zombie missions, Werewolf missions, Troll missions, etc. I hope so, or it will turn into too much of a good thing like the original Zombicide did if you weren't very careful.
All in all, I recommend it. It is a fun co-op zombie slaying game with swords and spells.
