I watched this on Friday, and thoroughly enjoyed it. The cast was great, and John Malkovich in particular delivered a very funny performance. Morgan Freeman was underused, I'm guessing because of his age. Speaking of which, it was great to see Ernest Borgnine, even though he's only in two short scenes -- at his age, we're nearing the last we'll see of this gem. Karl Urban had a good supporting role as the agent trying to bring Willis et al to 'justice'.
My big disappointment was that I'd seen most all of the good action sequences in the trailers. I know this is fairly typical these days, but c'mon, all of 'em? Also, one of the trailer sequences is a spoiler:
Overall, two thumbs up.
