I actually think that's the issue right there. It's just stuff you can already get from live action movies, so why bother watching an anime?
I mean, ideally, awesome stuff should be awesome regardless of its medium (live-action vs. animation). To say nothing of the fact that a lot of the shit pulled of in Black Lagoon, while technically doable in live action, would either be very expensive or dangerous to pull off. The mentality that animation should basically come in the "Fairly Odd Parents" vein or the "Family Guy" vein (with only a little variety allowed in between) is a frustrating part of American culture (queue excerpts from Academy Award voter ballots.......)
