Even the indie cinemas have this problem now. I went to see Oppenheimer at The loft Cinema in Tucson, Arizona and the projection was just awful. The frame wobbled, The focus seemed off, and the screen was filthy. I instantly regretted attempting to view the 70 mm version. It looks so much better on my 4K TV at home.

My indie theater has a bright blue pixel in their main screening room.

I complained about it when I first noticed, which was more than a year ago. It was still there the last time I went.
