The great tie-in fiction debate

[Albertosaurus Rex]

Heheh , nah just re the comment above, I am not sure that literary merit is necessarily going to be compromised by the fact that the books have a built-in fanbase and would be expected to sell well based on that alone.

That's not exactly what the argument is saying. What it says is that, because tie-ins will sell anyway, books that are sub-par are more likely to be released anyway. And the fact is that the tie-ins are likely to be more constrained. If it's based on a tv show, it will likely feature the established main characters. Worldbuilding will already have been done to a large degree. And not every author will have the opportunity to unleash worldshaking events, because otherwise the shared world would be doomed every week.

Once again, this is not saying that tie-ins cannot be good, but I can see the issues people have with it.
