Have you seen it yet?
If your not keen on blood then I suggest not going as there is an awful lot of blood and throat cutting. I didn't realise that the film was a musical type film, as I thought Johnny Depp was going to be singing just the once yet everyone seemed to have a go. Whilst the musical side of the film came across a little annoyng, it was still a good film and I recommend seeing it.
The film stars Johnny Depp, Helena Bonham Carter, Alan Rickman, Timothy Spall (plays such an annoying character!!!), Ed Sanders (Brilliant young actor/singer), Sacha Baron Cohen (Actually quite funny

) and many more!!
After having seen Sweeney Todd on TV a few years back with Ray Winstone this was a must see for me as I wanted to see how well it had been made and they got it perfect.
If you need someone to go with I'll go again
