My favorites that go along with the genre in this thread would have to be:

Saving Private Ryan
Revolver
Rock n' Rolla
Heat
BlackHawk Down
The Last Samuri
Sword of the Stranger
Ghost in the Shell
Fight Club
Kill Bill series
Jurassic Park
Goodfellas
Appleseed
Vexille

As far as more action and less content I'd add
Ninja Scroll (kind of cheesy lines but awesome violence and adult situations. Not for kids)
Pitch Black
Matrix (First one only. After the second one I didn't even bother anymore)
300
Other mediocre movies like those.
