Query: Very Dumbed Down, For... Like.. Teenagers Only, dude!

Very disappointed. The set looked so promising, but the in your face flashy attitude never lets up and the dumbed down commentary is just ridiculous. I really wanted to like this, but just cant watch this stuff. You try to learn something, but end up with nothing. A supernova "Whoa! Wouldn't want to be near that thing!" Buy these DVDs for young school children only or better yet just by Carl Sagan Cosmos or anything by BBC.
