Step 2: Realize that it's a Millennium Film and should be treated as thus. A dumb fun action film. Like pretty much anything they put out be they Expandables, the Has Fallen movies, etc...)
Those 2 steps will affect your overall enjoyment of this film exponentially. Not to say there are not many flaws with this movie. The jokes fall flat, there's not NEARLY enough Lobster Johnson in the film (Hell I'd pay good money to see Thomas Haden Church in a spin-off film reprising that character's earlier exploits( But I was able to enjoy the movie for what it was and not damn it for what it wasn't.
