I am not very keen on massive merchandise-spawning series and even less so on TV tie-ins. However, occasionally, a product appears that actually makes it clear that there is nothing wrong per se with series, merchandise or TV adaptations (I am still to see something originally created for TV that has been turned into a decent book, though. That if the original idea and execution is good, one can forgive (or even enjoy) a lot of merchandise lines and televisation too.
