Quick Question: United 93

I've been meaning to ask....to all those people who think it's "too soon" for a film about September 11, what did you have to say about Michael Moore's Farenheit 9/11? I don't remember there being any outcry about timing there.

I'd be happy to know what makes United 93 subject to the terms "distasteful" and "untimely" but not the former Farneheit 9/11.

I'd appreciate it if someone could shed some light on this for me.
