I don't quite understand the people criticising this film simply because it's a musical - what did they expect?
Sweeney Todd is a breath of fresh air, mixing horror with music and dark humour to create a truly unique musical movie. Top performances all around make this a must-own.
The Blu-ray itself is very nicely presented and features almost 45 minutes of bonus features that are missing from the standard DVD release. So. definitely worth opting for the Blu.
