In a movie theater, I am trying to get the best acoustic and visual seat that I can get. This is usually mid-crowd. If possibel, I'd like to also choose one that allows me view of the exits.

As far as priority goes... My first priority is to ensure the safety of my fiance and step kids. My second priority is to protect other people in the theater. The easiest way to do both of these is to end the shooting (most easily accomplished by ending the shooter). If the shooter is in the same room as me, he's an immediate threat as far as I'm concerned. If I have a clear line of sight, bang bang. Obviously in a crowded theater, it likely won't be as simple as that, but that's how I look at it.
