Root for the Bad Guy

This week's posts have placed this question in my mind: "When is it acceptable to root for the bad guy?" I think I have come up with some criteria that answers this question, but maybe this is all really a matter of perspective and one person's bad guy is another person's hero? I guess I'll let other people decide those moral ambiguities and I'll just stick to my analysis.
1. The Bad Guy's Enemies are even "Badder." - Certain movies, television shows, or video games feature a protagonist who is definitely on the wrong side of the law. However, since his main foils are all also on the wrong side of law, it becomes a question of who has committed the worse crimes. In some cases, the antagonist may have betrayed our protagonist, which automatically gives him the crucial sympathy card for the story. A sympathetic bad guy always looks better when held up to a greater standard of evil. Example: Payback - Mel Gibson's character is a thieving crook who makes a living by committing crimes, but he also was betrayed by his partner and is seeking revenge. Oh, and Maria Bello digs him, and that always makes you more likeable.
2. The Good Guys are Annoying! - Every once in a while a hero or heroine comes along that just defys any standard of acceptability. These problems often occur with annoying catch phrases, excessive success despite stupidity, and overall crappiness. Often times, the good guy may actually be the focal point of the story, but by the end of the movie, show, or game you just really don't care about them anymore and pray for their imminent demise. Example: Dead Rising - If you've ever played this game on 360 you know by now just how annoying almost all the survivors are. Once you get a group of the survivors up in the security room, all they do is whine and complain about their imminent death, which you would be happy to assist them with if your guns worked up there! Aagh!!! Somehow, Zombification for these people is strangely acceptable after you've seen just how annoying they can be.
3. The Good Guy Always Wins. - This is a major problem in television shows, where the good guys are constantly finding a way to outwit the bad guys, and sometimes in the most unbelievable ways. Eventually, you get so annoyed with the ridiculous ways the good guys constantly manage to pull it out that you just want to see them lose for once! After all, how many times can you see someone fail before you just want to see them succeed! Just once! Example: Wiley Coyote - how many times must our favorite carnivore be outwitted by some bird before he finally gets dinner? Seriously? How many times can we defy gravity, break the laws of physics, or have a fool proof ACME product go wrong? Another example: James Bond - Everyone's favorite secret asian man (that shouldn't be an esoteric reference, but I apologize if it is) constantly escapes certain death, even though we are constantly given the impression that the double-o agents have an extremely short life span. Imagine the scene:
Bond: You expect me to talk?
Bad Guy: No Mr. Bond, I expect you to die! (Bad Guy pulls out gun)
Bond: Wait, why don't you try cutting me in half with that death laser instead?
Bad Guy: Do you know how much it cost to run that thing? A bullet only costs a few cents! (Aims at Bond, squeezes trigger)
Bond: No! I haven't had sex with three different women in this movie yet!
*BANG*
Bad Guy: Ha!
Credits Roll
4. The Bad Guys are Just Cool... - Awesome costumes and kick-ass attitudes are just a couple of things that can make being the bad guy so fun. There isn't a better way to describe most of these characters than just "cool." Let's cut to three different examples in the three aforementioned genres: Movies: Darth Vader - Are you kidding me? Darth Vader may be the king of what it means to be a cool bad guy. From the moment he appears at the beginning of episode 4 you can practically hear "I am a badass..." Better yet, he ultimately turns "good" by the end of the trilogy, and you can see that he was tricked into the dark side in the new trilogy. So even though he is "bad" it just feels so good!
TV: Mr. Morden, Babylon 5 - Now THIS might be esoteric! For those of you that don't know about Babylon 5, shame on you! It was one of the best science fiction shows on television (it had an intentional 5 year run and no longer is on the air.) If you don't like science fiction, you probably won't like B5, but it probably has the most crossover potential of any sci-fi show thanks to a focus more on interpersonal relationships instead of space battles. So, back to Morden. Morden is the human representative of the "Shadows," who are an ancient race that believes in evolution through conflict. Essentially, Morden appears occasionally to manipulate the B5 regulars and create universal havoc, and he does it all while convincingly acting like the most bad-ass character on the show.
Games: Tommy Vercetti, GTA: Vice City - Never has outrunning cops, passing out drugs from an ice cream truck, stealing cars, and taking over the crime in a city ever looked so good! Vercetti definitely wins out over Carl Johnson in GTA: San Andreas based simply on the style factor. Getting into your Ferrari, wearing a white suit, no socks, while blasting classic 80's pop makes GTA: Vice City a complete joy, and adds enough "good vibes" to break up any of the darker side of the game.
