The Matador. Its a personal favorite, but not a great movie by any rate. I love how Pierce Brosnan seems to want to break away from the 007 mold and play the exact opposite: a sleazy assassin with no class and no friends and no love.
It's almost 20 years old at this point so that's part of it. But I do remember it was pretty under the radar when it came out. Nobody I know has seen it unless I recommended it. It's not the greatest reviewed movie, but reception was largely positive.
