Problems with 'Public Enemies' picture quality?

[I_Luv_The_Blu'z]

So what's going on with the 'Public Enemies' Blu-Ray? I'm really interested in purchasing it since I loved the film in cinemas, but I've been reading very polarized reactions in terms of the picture quality. Some say that it's incredible and that Mann's use of HD cameras really bring out the image, while others say that it is one of the worst transfers they have seen because of discolored pixels and grain. Are there some bad copies of the film flying around? Has anyone had any problems with the film? Finally, should I wait a little while to make a purchase? Thanks!
