The varying subject matter makes it hard to rate. Its informative, but often covers excruciatingly boring things that it feels like school.

Very informative, but wildly boring. Sort of like an owner's manual.

The ultimate show to watch if you are ill or otherwise too tired to be bothered to watch anything that moves too fast or has too much emotion.

It oddly reminds me of Mythbusters only without all the fluff. Thing is though, seeing how random things are made isn't nearly as interesting as a bunch of random experiments to prove or disprove everyday inquiries. That said, the show is alright. It isn't so boring you want to stop watching but it isn't particularly entertaining either. It's really formulaic and pretty much every episode is the same aside from what's being made.
