I have to agree. I just finished watching Weeds: Season 1 last night, and even my wife commented on the noisy picture. It's very inconsistent. Some of the shots are beautiful, but it's wildly inconsistent with compression noise, softness, and weird contrast issues. I guess shoving 4 hours of content on a BD-50 isn't such a good idea.
It certainly doesn't belong higher than titles like Ghostrider or Hellboy, which have a more polished and consistent image.
