I saw it when it first came out in theaters. Kevin Farley is no Chris Farley, even though they are brothers, but he makes a good Michael Moore.
All the terrorist having the name "Mohammad Hussain" was funny as well.
I liked it, though I went in thinking it was going to be more "Airplanesque" than it was, since the Zucker brothers were behind it, but it was a pretty good movie.
I don't know how the critics rated it, but back when I watched the "Today" show, if Gene Shalit panned a movie, I was the first in line to get tickets for it, while he raved about movies I have never heard of, usually some artsy-fartsy subtitled POS that would get great play at Cannes....
