It's a great start, but "It's not where you start, it's where you finish!", like the song says. Theater policies need to be more than just Ms. Patti NoPhone calling disrespectful audience members out, and when I went to see "War Paint", sitting in the front row, I made sure to remove my phone battery to avoid an "accident". I wasn't about to be "LuPone'd".
That being said, it would be nice to have a quiet theatrical experience outside applause and laughter and the occasional teary experience or gasp of shock (it shows that the audience is paying attention), but the sound of crinkling plastic, whether bottled water or twizzlers or other wrapped items and even on occasion the smell of fried foods followed by the crunch sounds would be nice to never have to experience again.
