The Spouse and I saw Sweeney Todd the other day. It's really good. Gruesome (in ways that the stage version can't be), but really good.
Johnny Depp, I forgive you for dating Winona Ryder.
Johnny Depp can actually sing. Helena Bonham Carter can mostly sing, though her voice is a bit thin for the part of Mrs. Lovett. The kid they got to play Toby is fantastic. Alan Rickman as Judge Turpin is, well, Alan Rickman.
My only complaints: no "Ballad Of Sweeney Todd" (apparently it's "too theatrical" -- they apparrently filmed something but ended up not putting it in), not even over the end credits; too many shots of Sweeney Todd's victims' bodies falling down into the basement (it's the landing part of that that clearly was giving Tim Burton the Happies); and not enough Anthony Stewart Head (who is in there for about three seconds; he was originally going to be part of the "Ballad of Sweeney Todd" chorus but that didn't work out).
Highly recommended. But not for the faint of stomach.
