sometimes I just enjoy laughing at movies/tv shows because they are so unrealistic. CSI is one of my favorites. 1st of all, with about 30 seconds of editing with their über software a blurry picture from a cheap video camera becomes an image with great quality, even though it's digitally zoomed 50x.
Also it puzzles me that how come everytime when they have no clue where or when the murder happened, they find an insect in the body. And of course the insect is some weird magical mongolian butterfly which only resides in a 20m x 20m area in the whole world. Also, finding eggs of that same insect (which they always find) means that they can accurately calculate the moment the dude was killed.
