I make it a point to not let any of my kids go to any big movie on opening weekend. I don't think I'm being paranoid I'm just trying to keep the odds in my favor when possible.
Sony and movie theaters are weighing their odds too. The chances of something happening are low but there's a what if in the back of their brains right now. I can't say I blame them or anyone else that has changed plans because of the "threat".
There is paranoid the sky is falling fear factory and there is don't needlessly place your self at risk. I think there is a little of both going on over this. I just cancelled plans to go into town because we're getting the first snow of the year. I know how stupid people can be when it gets a little slick. Limit risk when risk can be limited.
I really don't know what a rational reaction should be. I didn't plan on watching this movie before and don't plan on watching it now. There is plenty of stupid on TV if that's what I wanted to watch.
