Don't get me wrong, this set has some admirable qualities ESPECIALLY for the price. Most of my issues with this set-- red/green push, green tint, lack of brightness and eff'd gamma-- could be said about ANY of the 2011 models (save maybe the VT). So, in that regard, I'm happy I didn't pay any more than I did for these issues.
But, yes, at the end of the day I feel this set has a bit of a split personality. On one hand, this set is a killer media room display: the deep black and excellent motion make watching bluray a joy and gameplay is fast and furious thanks to the 16ms of lag. On the other hand, this set perpetuates the stereotypes that plasma is dim, buzzy, and prone to IR-- traits that are absolutely nonexistent on my 2008 Panasonic! Further, the lack of adequate picture adjustments makes some of the basic picture issues infuriatingly more detrimental than they need be.
Bottom line, if you can control light in your viewing room enough to watch in cinema and/or you aren't bothered by the unadjustable gamma and low saturation due to having to nerf your color control to avoid everyone looking sunburnt and sick... You'll be happy with this set. At this point, the price I paid combined with the the too-good-for-it's-class cinema picture quality has me hanging on even though I'm dissatisfied in other areas.
I mean, can I really complain when this 50" Panasonic cost me about as much as a crappy off-brand LCD? Seriously-- this set was CHEAP! Really, the only display that would likely make me happy would be an ST50: it doesn't push red/green, it has better picture adjustments as well as better gamma, and it's BRIGHTER! Unfortunately, it's also exactly twice the price I paid for my S! Some might call that a bargain... We'll see!

Edit: I should make a reminder here: my purchase of the S30 was largely an impulse based on price and needing a new smaller tv in our other room. At the price I scored the S I was willing to replace our 2008 panasonic 46pz800u that had broken my heart when it experienced the black rise. I am still wary of paying too much for a display as I really feel burned about my experience with that set-- but the price of the S was such that it didn't make sense to purchase something smaller when I could get an upgrade and move my large tv into the other room!
