Rules That Movies Should Obey

There are just certain rules that a good movie should follow, and because I love to make silly lists, here are a couple of said rules:

• Never Kill a Dog - NEVER.  I don't care if it moves the plot along, a good movie should never kill a dog.  The only movie I can think of right now that did this is that stupid alien invasion movie, The Darkest Hour, where the aliens are invisible and kill anything they touch.  It was a really dumb movie and then they killed a dog and it turned into a terrible movie.
• Don't Force Romances - I understand that in order to get men and women to come see a movie, you need a romance, but please don't force a romance on us.  Don't write a character in the movie just so you can trick people into coming to see your movie, it's unnecessary.
• Twist Endings Must Make Sense - A good twist ending is fun every now and then, but don't make a movie based entirely around a twist ending that doesn't make sense.  Or basically every M. Night Shamalamdingdong's movie after The Sixth Sense.  Seriously, water kills the aliens?  So dumb.
• No Stating the Obvious - I hate it when you are watching a movie and a character says exactly what is going on.  I can see it happening, I don't need the movie to also tell me what is happening.  I can't think of any examples right now, but you know what I'm talking about.
• Witty One-Liners Are Not Always Necessary - It was okay when Will Smith did it in Independence Day.  It was not okay when Will Smith did it in Wild Wild West.
• Eye Candy Characters Must Be Believable - I'm looking at you, The World is Not Enough.  Denise Richards should never play a nuclear scientist and she certainly shouldn't be named Dr. Christmas Jones.
• Don't Substitute CGI for Plot - This seems to be a growing trend in Hollywood right now.  Movies like Wrath of the Titans, 47 Ronin, and the soon to be released I, Frankenstein seem to think it's okay to just throw a bunch of computer graphics on the screen and hope the audience doesn't notice the plot is nonexistent.
