1. The Walking Dead. It's beyond me why people like this show, insofar as it is just like the primary antagonists of the series: it is slow, it is mindless, it stinks and it just won't die. The reason why I mention it now is because at the end of the first season (the only one I got all the way through), the CDC scientists "explain" the zombies as some sort of bacterium or virus that reanimates the dead by attaching to the cerebellum and cerebral cortex, thus "bringing back" the person. However, the zombies don't receive proper nutrients or oxygen to allow for any of the thousands of energy exchanges needed to keep muscles functioning or organs running. Without that, the zombies should have rotted so much and so quickly in the open air that, after a few rains, none would be left except those created when survivors were too stupid to burn their dead or kill and burn infected members. And that's not a lot of zombies, anyway.

2. Time Travel Movies. There are dozens movies in which people travel back in time and meet people from the past who (a) speak perfect modern English, (b) have all their teeth, (c) have no hideous scarring from smallpox or other skin diseases, (d) never lost eyes, arms or legs in battle, (e) stand as tall as modern people and appear to be well-fed, (f) don't stink to high heaven and (g) more often than not exhibit character traits of the modern age.

3. Idiot Exposition. Hollywood movies often have way more explanation than necessary, so that stupid people can enjoy movies that are already really stupid. Sadly, many times this exposition is at times when people wouldn't even bother saying a word. Case in point: Mission Impossible with Tom Cruise (I'm sad to have to admit to having seen it). He has some stupid gum that is plastic explosive and the catchphrase when it was explained was "red light, green light". So when he's hanging from a helicopter in a tunnel or something and has 2 seconds to save the world he repeats the phrase. Thanks, dipshit. The people with brains who haven't already left the theatre in disgust didn't need the refresher on something they saw just a half hour before. The others should just be euthanized anyway. A variant of this is the drawn-out death exposition, where someone explains everything before dying. I am particularly happy that Breaking Bad intentionally has people shot in mid-sentence.

I could go on and on.
