Fortunately, years ago, I took a screenshot for just such an occasion:
And wonderfully written rant, McStudz. It perfectly sums up my feelings towards both the younger demographic of The Simpsons and the declining quality of the show over the years. Saying that The Simpsons is an ideal LEGO product because it's a show that kids enjoy is like saying that South Park or Call of Duty would be ideal LEGO licenses as well. Yes, kids watch South Park and play Call of Duty, but that doesn't say anything about their appropriateness as a potential LEGO product, because those kids aren't the target audience. Kids aren't the target audience of The Simpsons, either. And I know LEGO has licensed PG-13 films such as Pirates of the Caribbean and Lord of the Rings, but those are all a completely different genre from The Simpsons - they are all "fantasy/historical action adventures", which has always been something that translates well to LEGO products.
Some things are just better off being left to the MOCers, in my opinion. Want to make MOCs based on this show? Go right ahead! But LEGO licensing it, and seeing these products take up toystore shelf space... ah, well, listen to me, a crummy old-fashioned LEGO fan.
Sounds like the future of LEGO Simpsons depends on the success of the first wave. As much as I hate to admit it, that younger demographic does probably overlap considerably with LEGO's demographic, meaning these sets probably will be successful, allowing LEGO to milk this license for years to come...
