Your Opinion on Teen Mom shows?

I'd really like to hear opinions on shows like 16 & Pregnant, Teen Mom, Etc. Even opinions on TV shows such as Kate Plus 8, and Octomom. In my personal opinion, especially the pregnant teen shows are just about immature girls who throw temper tantrums and blame their parents/boyfriend for every little thing. I also feel bad for the children of the moms, because they're getting exploited before they can even talk! In Kate Plus 8, I think the same type of thing occurs. Kate and her now ex husband start drama and exploit their children. Granted, sometimes these shows do show the hardships of being a young parent, but mostly they are rewarding teens for making a bad choice.
