Comic book adaptions of TV shows


Does anyone read comic adaptions or continuations of TV shows?

It seems like more and more cancelled series are having new "seasons" of stories by publishing comics instead. Buffy the Vampire Slayer, Angel, Firefly/Serenity, Charmed, and Smallville have all done it. It seems like an especially common thing for sci-fi and fantasy series to do, since they can have a much bigger "effects budget" in comics than they ever could on TV!

I personally have read the Joss Whedon series ones, and I find them entertaining, although it's definitely not the same as having an actual TV episode. And I do like comics and graphic novels, in general. I guess in a perfect world we could have new episodes AND new comics...
