That was a refreshing read! (No, I'm not being sarcastic.) And my commiserations for having to watch it dubbed. I was half thinking that Swedish cinema was going to do that too (they have this tendency to regard everything animated as children's films), but they didn't sink that low, fortunately.
I can sort of see why the reviews have been so positive amongst critics and media and suchlike - the thing did exactly what they wanted it to do.
Personally, I think it was so popular because it rose from the level of mind-numbing mediocrity of the show's latest few years.
I thought Homer's meta-joke right at the start was lame, though I might have found it funnier if it hadn't been spoiled to me by a review. My theory is that they did it because "South Park: Bigger, Longer and Uncut" already did the meta-humour thing of having the characters go and see a film based on their favourite TV series. Yes, South Park already did it.
Seems we agree about Colin. *Can't* the writers not give Lisa a love-interest who is either damaged goods and/or jerks (Ralph, Hugh, Nelson, Milhouse) or a bland Gary Stu who apes all her interests (Thelonius, Colin)? Because, you know, it's not that important that eight-year-olds have boyfriends... they might as well not try.
I suppose Hugh is the most interesting one, since he started out as a perfect guy (if a lot more interesting than, say, Thelonius) and turned out to be a jerk of the lowest order. Dunno if that defeats my model or not.
