Oh hell, Ken and I went to McD's
immediately after watching SSM, because we started craving it. Heh.
I hate movies that show "too much of this is a detriment". Um, too much of ANYTHING is detrimental. It's like a friend of mine who showed me "how bad Pepsi is", because this guy substituted his entire water intake for 2 weeks with Pepsi and tore up his insides. Um, duh. Hell, if he did that with organic orange juice, he would have torn up his insides much quicker, due to the acid. That doesn't mean orange juice should always be avoided.
Another friend of mine read "Fast Food Nation", and told me to never eat another hamburger, because there's ecoli/poop in the meat. Yet, she buys organic fruits and veggies grown in natural fertilizer (which does contain ecoli/poop), and only uses water to wash them off.

At least the meat is getting cooked.
I've always been from the school of thought that moderation is key. And anything in mass quantities is bad.
