I love this show. At start, I found the way the cartoons were drawn was really weird, but after one or two episodes, I ended up enjoying this show. All episodes are really interesting.
One thing I also love about this show is how the character "Mo", at the end of every episode, gives the viewer a little history lesson regarding whatever the episode was about. (For instance, I just finished watching an episode where "Hitch" found a watch that when its time was adjusted, it'd act like a time machine, and at the end of the episode, Mo explained how time used to be measured in ancient times.) It's really just like a couple of seconds, but it's still pretty interesting.
I'm surprised there's such few (at the time I post this comment) comments on this show. I reckon it should be a little more famous. It's really good!
I highly recommend it to anyone. If you ever catch this on TV, don't change the channel.. the cartoons are weird indeed, but just watch 'em and you'll realize the are very interesting indeed. ;)
