I have the 55" 55PFL5907. One thing I noted was that a couple of the TV's had different refresh rates depending on the size. One of the middle ones was more m.s. that the others. Weird.
Anyway, I tried the suggestion calibration settings on cnets review of the PFL5907 and I found it...close to pleasing.
Although it does seem to have a slight blue tinge like they mentioned you can get it pretty close to good with adjustment, and I don't think my TV was as bad as theirs.
I found that with the CNET calibration list the oranges and reds were close but a lot of peoples faces seemed to have a thing where they looked like they were wearing very heavy blush.. like it was popping the reds out in their orange faces way too much.
Overall I readjusted to make that go away at the expense of the reds looking a little orange, and didn't adjust the blue down as much as they suggested, and I got the colors to acceptable enough levels match for my eyes/likes.
Not perfect but good enough to not notice any weird shades randomly when you're immersed in a movie.
I have the truemotion set to medium for movies or high for sports despite cnet's ever hating on the motion enhancers.
The one thing I have to say about this TV is the motion is far better than my 4 year old Visio (which was the upper tier visio around that time) and my 5 year old Sony bravia.
IT doesnt seem to look as..... liquidy as some of the other true motion 120/240/etc tvs out there...
But it looks very natural and hasn't had any jerking and very few artifacts even on high compared to my previous two TV's.
I have to say the motion is far superior, and the lights/darks are great.
There is a little bit of bleeding around the edges when the screen is extremely black, not noticeable during dark movie scenes so much as it is once in a great while between scenes or a commercial where there's an unusually long sort of cut that leaves the screen fully or almost fully black.
Overall, to sum it up very clear picture, very good motion, color is good enough with adjustment, light dark contrast is good, only a tiny bit of black light bleeding with 95%+ black on the screen.
I am happy with the purchase. The tv fits my dimensions to the 1/8" (awesome) and seems to have a good response/refresh for games/computing, so it suits my needs.
I wish it had been a little cheaper for not being a 3d tv, but...yeah I'm happy with it.
