I love 3D movies and have (or had) several 3D capable plasma displays. BUT, the novelty has worn off. On the rare occasion that I (or we as a family) wanted to watch a 3D movie, it was always a pain in ass getting our active 3D glasses ready to view a movie. Either the batteries were dead, the glasses weren't charged or we simply couldn't find the glasses.
Perhaps a passive 3D solution would have been the better option, but I hear they don't work as well.
In the end, we just enjoy seeing the occasional 3D movie in the theater now, usually in IMAX. We have graduated to 4k with Dolby Digital HDR and that is probably more impressive than yesterday's 1080p 3D.
