The THX optimizer is based on the individual movie, which means you really need to calibrate then for each movie, which is not practical. The early THX optimizers were tested by Joe Kane and he showed the patterns to often be wrong. I believe they have improved since then. I find them useful for those who don't have a good calibration disc, such as Digital Video Essentials or Avia. I did like you though and ordered a pair of the blue lens glasses from THX and then picked up digital video essentials.
