Brides is an exaumple of hammer at its peak. Yes the script doesn't hold up to close examination but that isn't important.
The costumes, the lighting and the performances make this one stand out from the crowd.
Cushing is on top form and Yvonne Monleur is simply stunning. Add to all that a truly iconic Count played by David Peel and you have one of the best gothic fairy tale/horrors ever made.
