A common misconception is that tie-ins are poorly or quickly
written, and while some have seemed that way to me, as my reading
tastes have matured, I've been able to choose better-written material.
What makes me personally pick up a tie-in novel or comic book these
days? The author has to have some experience writing for the original
medium and the new one, as Monk novelist Lee Goldberg has with USA
Network's Monk. Because Goldberg has written for the show, and because
he is a novelist in his own right, he's well suited to bring Monk to
some ways, tie-in writing is more difficult than creating characters
and a story from scratch. Tie-in writers have to deliver the best of
both worlds: what the existing fan base enjoys about the original
concept and what the new fan base expects from the new concept. For
example, Tod Goldberg's first tie-in, Burn Notice: The Fix
delivered the wry spycraft from the TV show but also delivered an
intricate plot better suited to a novel than to TV's usual 44 minutes.
