Hi EZ! Well, you and I are polar opposites in The Simpsons Department!! I've been watching it since it came to Australia in 1990, I was 11 or 12!! I not only watch it regularly, but I used to record each episode, but now that the DVDs are out, no need!! I know most episodes intimately, often word for word. I saw Nancy Cartwright (the voice of Bart) in concert, and won a Simpsons quiz against two guys, which scored me a signed T-shirt! One of my proudest moments!!
This movie coming out is a momentous occassion in my life and I can't wait! It's hard to believe you guys haven't seen much of the show, as it's hard to avoid I think. But if you're not into the humour of it, then why waste your time, you know? For me, there's so much to love about it, it's funny on many levels at the same time, and they're terribly good at political and social satire, without coming off as arrogant or malicious. There's really humour of every kind in each episode, which is probably why people from all walks of life/political leanings/levels of intelligence can get something out of it. I know that some people have trouble getting past the fact that it's animated, as a lot of adults seem to think that's for kids, but I can assure you there's plenty there for adults.
It's a show you can pick up at any point and not have to know a convoluted backstory to understand what's happening, so if you want to give it a try, just tune in sometime!
