Must admit I havent seen it and want too but I am a little put off by the singing parts added, Why couldnt it just be a good ole fashioned gory horror like the rest of the adaptions have been? Dont get me wrong I love musicals as I obsess over Phantom of the opera and a few others, but why do it???!!
When you watch it you'll understand why it's a musical rather than a normal film. The musical aspect really works, in fact I wouldn't want it any other way - and I hate musicals with a passion. They did a brilliant job with it.
Im always willing to be proven wrong as I have watched some questionable films over the years and been blown away by them! Might rent it out soon and try it for myself! :)
