Same thing for me, though granted my local indie also played NTTD and is playing Death on the Nile right now. I saw Worst Person in the World today, and not only did they play The Batman trailer, one of the managers popped up in the middle of the trailer and gave a long-winded explanation about why they were playing the film at their establishment, I guess to avoid making the artsy fartsy folks angry. How it's basically a film noir and is reminiscent of The Big Sleep and Silence of the Lambs, so it fits with what they play.
Like dude, just admit it's because you don't have anything else to play for the Spring line-up.
