Whilst not quite as good as some of the other great, weird horror movies of the 30s (Freaks, Island of Dr Moreau, The Black Cat), it really works well whenever the zombies are on screen. It works less well in the stagey, ridiculously melodramatic performances, the ridiculous pauses to indicate significance, and Lugosi being Dracul-ish at every opportunity.
However, I did definitely enjoy the zombie/walking dead parts, and can happily ignore the pointless scenes, the constant Lugosi hand-gestures to indicate he’s turning up his mesmeric power to 11, and enjoy the odd tension, the pretty ‘white zombie’ of the title, and the vulture that looked distinctly like an eagle. Oh and a pretty good ending.
