I’ve practically memorized all of Tom Clancy’s Jack Ryan novels, so I knew "Sum of All Fears" wouldn’t compare favorably to the book. However, as a thriller, this is a good movie, and it’s very topical, as we see terrorism on TV on an almost daily basis.
[2009: My how times have changed. I've come to dislike the jingoism and ends-justify-the-means mentality of Jack Ryan. In addition, there's terror fatigue, as we've been hearing people yell "Terrorist!" at the drop of a hat for the past eight years. I don't think I'd be so charitable as to give "Sum of All Fears" a 2.5 today.]
