Some of the best comic book-related entertainment has to be DC’s Showcase. One-off episodes of some sometimes obscure characters and groups. While not really tied to any singular continuity, all are very entertaining. I would love to see Challengers of the Unknown given the DCS treatment. The format would make a great anthology series for television or a streaming service. Perhaps they could roll out one or two of their mystic characters to host each episode.
Kamandi almost knocked my favorite down a peg but it has to still be the Sgt. Rock short where Rock loses Easy Company and is assigned replacements for a new mission. The new team was a wonderful homage to the Creature Commandos. The CC first appeared in Weird War Tales number ninety-three. The chances are slim of seeing the full line-up but you never know.
Are these streaming anywhere?
You can find some on YouTube but others are more difficult to find without purchasing the material.
