International friends have mentioned it wasn’t an issue, because they had subtitles and could keep the film at reasonable volume, and they overall enjoyed the movie.
Maybe it was intentionally designed to eliminate the English speaking audience. But multiple viewings won’t help you.
I can’t wait to watch it at home so that I can properly digest and enjoy the movie.
Slightly off topic, but I personally use subtitles for everything I watch now because I got tired of missing dialogue for different reasons. More movies being on demand is a blessing for me in this regard.
The only genre I do not turn subtitles on for, is stand-up comedy, for obvious reasons.
But overall, I'd rather Christopher Nolan sit in a normal theater and listen to it before he signs off on the final sound product.
Excellent movie otherwise, and I look forward to watching it again with subtitles. (Although it's possible I already have.)
