The ending has an interesting twist.
Moria says, "In many regards, Mark of the Vampire is a better film than Tod Browning’s Dracula, even if it remains wholly in Dracula’s shadow". 1000 Misspent Hours, on the other hand, calls it "a mercilessly dull, ineptly edited film with an acutely offensive cop-out ending". Classic-Horror.com says it's "a very atmospheric, chilling vampire classic. A must see for all vamp fans and a can’t miss for all classic horror fans."
