Saw it today and thought it was excellent, the gore was very well done, JD was great as Sweeny and HBC fab as Mrs Lovett (though for some reason I can't stop calling her Mrs Miggins, the pie shop owner from Blackadder). I am a musicals fan so I enjoyed the singing although they rushed through 'Worst Pies in London' so quickly that quite a bit of the humour was lost.
I hate Sascha Baron Cohen with a passion but his appearance didn't annoy me too much and the little boy was great. I thought the two romantic leaRAB if you can call them that were not the best but then neither had much of an impact.
My greatest praise though is for Alan Rickman and Timothy Spall both of whom do bad guys so brilliantly.
