Chick Flicks and Hallmark Movies

The two types of movies named in the title are the most irksome types of movies around. Yes being a girl I enjoy the occasional chick flick because they always end happily and involve some sort of complicated romance, but if you think about the concept of chick flicks too hard you eventually feel sad because you know that there is about a one in a million chance of what happened in the movie ever happening to you. Chick Flicks usually involve a girl finding the perfect guy and in turn finding true love. A girl who watches too many chick flicks usually gets into the mentality that it is incredibly possible to fall in love within a week and get married to live a perfect life with the man of their dreams within a month, now call me a cynic, but that is never going to happen, at least not that fast. The fact that the girls in these movies always end up getting their hearts broken and then mended generally by the same guy is also depressing because I'm sure that pretty much every girl out there knows that said scenario is generally not the case. Also chick flicks are generally incredibly predictable, the viewer knows exactly how the movie is going to end the moment all of the characters are introduced, where is the fun in watching a movie when you know how it's going to end? The same is true with Hallmark movies. They usually portray a 'real life' situation in which some sort of problem arises and then is resolved through a bunch of family-friendly events. Hallmark movies are meant to teach a lesson about family and love that either most people are already aware of and do not need pounded into their heads or other people don't care about. (Disregard the last part of the last sentence, I realize how confusing it reads.)

My question is how on earth do these movies manage to flourish in the box offices and on TV?
My point is that these movies are pointless, depressing, and stupid when watched over and over, but okay for the spontaneous/occasional viewing.
