The problem here is quite simply that you are taking flaws that are present in many LCD panels and attributing those flaws to all LCD panels in a universal way. By analogy, it would be as though, if some of your relatives were known to be liars, that I went around saying that the problem with your family is that you are all liars.
The off-axis viewing issue is one example of this. This is unquestionably a problem with many LCD panels, but it is definitely NOT a universal problem with LCD panels. It is logically dubious to take a flaw that is generally present in some category of thing and claim that it is universally, invariably a flaw with that category of thing. That is exactly what you are doing, and it is simply B.S.
The same applies to your claims re the 120 Hz refresh rate. The 120 Hz refresh rate is not even an intrinsic part of LCD technology. The technical property of LCD molecules that can potentially lead to motion-related artifacts, is the hysteresis of the molecule, i.e., the resolving time for it to return, from the form where it permits light to pass, to the form where it does not permit light to pass. It has been true that the hysteresis of the molecules was generally so great as to cause motion smear. This is certainly not universally true of flat-panel LCD televisions today.
It was only necessary to reduce the hysteresis to the point where motion would look the same on an LCD panel using a 60 Hz refresh rate as it does on a CRT set using a 60 Hz refresh rate. But it is manifest that the resolving time of the molecules was decreased to the point that it even offered the potential for doubling the screen refresh rate. As I previously explained, it is not difficult to imagine ways in which this could be done poorly. In particular, if reverse 3:2 pulldown is applied to film-based content to extract the original 24 frames per each second, then exactly four additional frames have to be inserted between each of those original frames. The simplest way to do that will be by simple repetition of the original frame, in which case the effect that you see on a good, state-of-the-art flat panel LCD TV is for every intent and purpose the same as what you see when you watch that film-based content in a theater. When I watch DVD's sourced from film-based content, the motion looks entirely the same as motion looks when watching a movie in a movie theater. The inherent jerkiness of fast motion captured by a 24 fps film camera is faithfully preserved.
