This show is worth watching but sometimes meanders through "connected" topics that really aren't very connected.
For example, if topic A makes you want to complain you can do it by ground mail. So let's talk about ground mail. That's not a connection. If you make the topics more thematic and connected it helps with learning. For example, if every example had something to do with the history leading up from ancient times to how modern gears work.
At intervals the program stops to recap. That's an acknowledgement that the various connections are hard to follow. Also, many of the topics are either repeats from the previous Connections series, or aren't science.
Finally, the show is full of cute verbal flourishes that undercut the clarity. Things like "He was all abuzz about bees. Well, insects. Well, any creepy crawly thing." Or "He failed. Mind you, he did succeed in one thing."
What? I'm just trying to understand. Stop taking back what you said and obfuscating. It's fine to have fun flourishes, but make them support clarity.
For whatever reason, this doesn't have the power of the original Connections TV show.
Still, you might learn a few things. 7 stars.
