Don't let the title turn you off.

Rating: 8/10 (7 April 2006)

The law of retaliation. It's the primary law that New York crime bosses live by, at least according to Lucky Number Slevin. Unfortunately for Josh "Squinty-Eyed" Hartnett, a case of mistaken identity drags him right into the middle of this law in motion.
"Lucky Number Slevin? Come on, Johnny! That's the stupidest title ever! And Josh 'Wooden Boy' Hartnett?" I know, I know. I thought the exact same thing when I originally heard the title. "What kind of lame attempt at being clever through the use of a silly pun is this?" I thought to myself. But the title actually makes sense within the context of the film. To say anymore would reveal too much of a major plot element, but it's a moment where you'll say, "Ah, I get it now. OK, that's not so bad." And seriously, I want you to use that exact quote so I don't look silly.
"Too late!" Gee, thanks. As for Hartnett, I'll be the first to admit that I'm not a charter member of his fan club. I typically hold him as the standard bearer when I need a reference point for listless, unemotional acting. But the guy gives it his sarcastic best here and delivers the most likable character I've seen him portray.
It doesn't hurt that he's surrounded by a strong cast of actors playing a variety of entertaining, eccentric characters. Lucy Liu is cute and inquisitive. Bruce Willis is a hit-man who you truly believe is a stone cold killer. Morgan Freeman dares the audience to still like him considering the fact that he's a crime boss. And Ben Kingsley, after a huge slump of horrific movies (A Sound of Thunder, BloodRayne) finally gets quality material to work with.
As much as I enjoyed the quirky characters, what really won me over is the movie's slightly complex and somewhat unpredictable plot. Following the nonlinear storytelling of Lock Stock-era Ritchie, Slevin sets up the basic premise and then the audience watches as the pieces of the puzzle fall into place. You may be able to figure out where everything is headed by the halfway point, but it's still fun to watch how it gets there.
You may also be able to find a plot hole or two if you look hard enough, but I enjoyed the film too much to worry about such silly nitpicking. If you're one of those spoilsports who brings your industrial-sized nitpicker to every movie with you just so you can find things to complain about then just stay home and let everybody else watch it in peace.
I can understand the argument that some of the dialogue feels a little contrived in an effort to appear clever, but it didn't bother me. I can recognize the humor in lines such as, "Tell it to the one-legged man so he can bump it down the road," and character reactions to quotes like this reveal that it isn't written to be pretentious, just knowingly different.
If you're looking for a recent comparison then I'd say Slevin has a similar feel to 2005's highly entertaining Kiss Kiss Bang Bang. Though Slevin isn't as consistently funny, it employs a similar dark comedy style and I think it has the better story and more satisfying ending of the two.
If you're not easily offended then you might want to check out Lucky Number Slevin. Be warned: there are a couple of quick, gratuitous sex scenes at the beginning of the movie that feel thrown in just for the sake of pleasing the "perverted male" demographic, but as far as style goes we need more movies like this that put forth a little extra effort to be cooler, more clever, and smarter than their peers.
THE GIST
If you like movies with quirky characters and a complicated plot that requires you to willingly keep everything straight in your head as you follow along then Lucky Number Slevin certainly will entertain.
