: There's nothing wrong in my book with commercial merchandise, as long as it
: doesn't affect the actual canonical content. Paris is still beautiful
: despite the tacky gift shops. It's when it created a feedback loop with
: actual content that it becomes a problem (the equivalent of tourist traps,
: e.g. Cars 2).

: The feedback loop can take one of two forms. One is that bad stories are told
: just to keep the franchise going. The other is that the actual content of
: a story is modified to better merchandise.

This is true, and I should have said something similar in my original statement. I guess I just have a pessimistic view and tend to assume those feedback loops are going to happen.
