This might be a factor in why some think the movie is drab looking?

That was definitely a factor in my enjoying of the film.
But it was 12:30 when the film was done and I’ve already complained at this establishment about dim pictures before and got absolutely no response from the management. “We would know if the projector was dim”.
I knew it was a cheap theater when I went there so I didn’t press the issue.
