imo it's by far the best season of the show. The animation style was at it's peak, and the expressions of the characters had none of the stiffness of later seasons, and it looked nice and hand drawn unlike the glossy cgi style of newer episodes. The jokes were well written and much funnier than later season jokes which are somewhat... family guy esque. I only first saw this season last year, but it seems fresh, indeed a lot fresher than say the Scully 'Homer is a idiot' episodes which i am quite tired of. There's only so many times you can watch Stupid Sexy Flanders and think it works before you get sick of the gag. Also in this, imo the best season of the show, Lisa isn't quite as annoyingly hippie and environmentalist as in later seasons, being more normal like Bart (although not as normal as in the shorts, which is the peak of her character imo before Simons ruined it and made her into a hateable nerd). Bart is in this season in his peak of character and it is this season that features bart being most normal. Indeed the show itself seems most normal during this season. In season two i think they ruined the show by 'improving' the animation and losing much of the character in the process, also by making Homer more stupid and less angry. Bart should be good old normal Bart, and Homer shouldn't be an idiot, he should be a normal father who gets angry at lots of stuff. And Marge shouldn't be cool with everything, she should be trying to fit in and going to church and doing normal things. Lisa should be punching Bart and being normal rather than being a treehugging beatnik layabout, and Maggie... well she was just better in the first season. Jimbo Kearney and Dolph were much more normal too before they became background characters in every episode. And the music and style of the show were much better too in this season.
I tell you season two ruined that show.
