Okay.
You clearly didn't watch the whole series.
The thing about Bebop is, yes, they are all stand alone stories but it is the character's back stories that ties them together.
If you watch the whole thing it becomes readily apparent why Spike and the crew are the way they are and how and why they interact with each other.
Also, just finished watching Ghost Hound. Not bad at all.
I love a good mystery and the horror/ghost ascetic is pretty cool.
Would love to see more like it if you guys have any suggestions.
