I like them, have been to over 100 in the theater and own a few 3D Blu-rays as well. If a movie is in 3D, I go to that version exclusively, and only twice that I can recall have I not (Miss Peregrine's where I waited too long and the theater yanked the 3D version, and Billy Lynn's where the 3D didn't come to my town). I even went to No Time to Die in 3D, and I'm not sure a lot of people even knew it was released in 3D (I didn't know it was going to be). The only issue I've ever found is the slight dimming that happens with the specs, though that varies between theater and auditorium. Sometimes the bright levels have been excellent, as good as any 2D movie.
