Television

"Does TV provide a good form of entertainment?"

The question as to whether or not TV is a "good" form of entertainment is hard to answer. If you, Mr. Logsdon, mean to ask if it is an effective way to be entertained, then the answer is yes. If America is in the mood for comedic, dramatic, romantic, violent, or otherwise specific mood, it can be found somewhere in their 70-500 channels accessible from the comfort of their own home. It can (and sometimes is guaranteed to) keep us entertained for hours or even entire evenings, and with DVR/Tivo and more channels than ever available, the already effective system is also ever growing in its ability to glue us to our furniture and burn as few calories as possible.
If you mean to ask if it is a healthy, social, typical, or otherwise positive use of time in the pursuit of curing boredom, then the answer is definitely no. Picture the movies set in the 80's and 90's. Kids were throwing ball with their dads in the front yards, or throwing a football in the street outside an apartment. When they walked inside, it was more likely to crash on the couch after a long day of play than to sit there for hours to stare at a screen. Picture the movies we watch set before that era. Were there even TV's in houses? Not often. Back then, it was an oddity to spend half as much time as we do in our living rooms or bedrooms just watching something.

TV is something we are not evolutionarily ready for. Our genes want us to get up and consume energy as we acquire it. We eat, work, eat again, work some more, eat one more time, and then what? Watch TV until we get tired and drag ourselves to bed. This mixed with our high fat diet is a tragic ironic situation in which our own evolved minds produce an environment so fast our bodies are used to being active and stimulated in the old environment and stimulated and don't take well to watching television.
