I'm not saying that, just saying that I find the interpolation done on most such sets to be off-putting. I would assume it can be disabled on most sets, but I'm not sure. I think main appeal in higher-refresh sets is for compatibility with 24p sources, but I'm not very up-to-date on it since I'm still getting by just fine with my clearance 37" LCD from 2006
I have a 120Hz LCD monitor for my desktop PC, but that's a whole different beast as it actually accepts 120Hz input from the PC itself. Very nice for gaming, and I guess theoretically it should be better for movies, too, though I've never bothered doing a thorough comparison with my old monitor.
