I had to exchange my 46" twice to get a set with acceptable cloudiness. Note, if you get one that has none - you are luckyThe Bad
TV occasionally locks up when using the Netflix App.
Tuning the TV was a MoFo
Clouds are only apparent in extreme dark scenes, channel changes and if you get a decent set (and tune it) you will not notice it 99% of the time.The Good
I have had the TV (on and off) for over 3 months now. I can say that one of the reasons that I bought a Sharp was based on their customer service reputation. Although it was a Pain in my A** - they replaced both sets. Having a problem with your new electronics is quite a depressing thing when you are trying to tune out the clouds at 3AM!! Follow that up with some bad customer service and you lose a customer for life... but Sharp took care it for me.
I feel as though I have this baby tuned about as good as I can get it. Note that I will turn the active contrast or OPC on/off depending on the the individual bluray or show that I am watching. This manages any poor blacks and the cloudiness to the point that I find acceptable.
The color and crispness is a joy to watch with the following settings. Note that I would not typically take the time out of my insanely busy schedule - but when the first set was a lemon this was the only place that I had to turn to and it did create a small sense of solace (thanks IMWS).
Try these - you will be glad that you did

Again, you may want to mess around with some of the settings like DNR, motion enhancement, etc.
Last thing - I have the picture mode set to dot to dot (or something like that ) so commercials and standard TV doesn't look like crap.
